We look at the division of 77708345 by 601 
The aim is to understand the frequency of 601 in 77708345.

Advancing to step 1:
601 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 601

Let's proceed to step 2:
The number 601 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 601

On to step 3:
When dividing 777 by 601, we get 1 with a remainder of 176.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 601 from 777 and we're left with 176.
Fetch the next digit (0) from the dividend, attach it to 176 and continue: 1760 / 601

Advancing to step 4:
If we divide 1760 by 601, we get 2 and a remainder of 558.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1202 away from 1760, we end up with 558.
Grab the next digit (8) from the dividend, add it to 558, then carry on: 5588 / 601

Let's proceed to step 5:
601 goes into 5588 9 times with a remainder of 179.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 5409 from 5588 to get 179.
Fetch the next digit (3) from the dividend, attach it to 179 and continue: 1793 / 601

Let's proceed to step 6:
601 can be fit into 1793 2 times, resulting in a remainder of 591.
The number 2 becomes the next digit in our result. 
Result so far: 1292.0
Deduct 1202 from 1793 and we're left with 591.
Take the next digit (4) from the dividend and append it to 591, then repeat: 5914 / 601

Step 7:
601 can be fit into 5914 9 times, resulting in a remainder of 505.
Use 9 as the next digit of our solution. 
Result so far: 12929.0
The remainder is 505 after subtracting 5409 from 5914.
Grab the next digit (5) from the dividend, add it to 505, then carry on: 5055 / 601

Step 8:
When dividing 5055 by 601, we get 8 with a remainder of 247.
The number 8 becomes the next digit in our result. 
Result so far: 129298.0
The remainder is 247 after subtracting 4808 from 5055.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 9:
If we divide 2470 by 601, we get 4 and a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 129298.4
If we subtract 2404 from 2470, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
601 goes into 660 1 times with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 129298.41
Subtract 601 from 660 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 11:
When dividing 590 by 601, we get 0 with a remainder of 590.
Write down 0 as next digit of the result. 
Result so far: 129298.41
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
The number 601 fits into 5900 9 times, leaving a remainder of 491.
Record the quotient 9 as the next digit in the result. 
Result so far: 129298.4109
If we subtract 5409 from 5900, we get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 13:
If we divide 4910 by 601, we get 8 and a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 129298.41098
If we subtract 4808 from 4910, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 14:
The number 601 fits into 1020 1 times, leaving a remainder of 419.
Write down 1 as next digit of the result. 
Result so far: 129298.410981
If we take 601 away from 1020, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

On to step 15:
4190 divided by 601 is 6 with a remainder of 584.
Record the quotient 6 as the next digit in the result. 
Result so far: 129298.4109816
The remainder is 584 after subtracting 3606 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 16:
The number 601 fits into 5840 9 times, leaving a remainder of 431.
The number 9 becomes the next digit in our result. 
Result so far: 129298.41098169
Deduct 5409 from 5840 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

In conclusion, the division gives 129298.41098169 with a balance of 4.31e-07.
