Let's divide 90860425 by 77
The aim is to understand the frequency of 77 in 90860425.

Let's proceed to step 1:
The number 77 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 77

Advancing to step 2:
90 divided by 77 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 77 from 90, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 77

Advancing to step 3:
77 goes into 138 1 times with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 77 from 138 to get 61.
Bring next digit (6) of the dividend behind the 61 and repeat the process: 616 / 77

Step 4:
If we divide 616 by 77, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtract 616 from 616 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 77

Moving on to step 5:
If we divide 0 by 77, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 77

Moving on to step 6:
The number 77 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 11800.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 77

Step 7:
If we divide 42 by 77, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 118000.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 77

Advancing to step 8:
When dividing 425 by 77, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1180005.0
Subtract 385 from 425 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 77 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1180005.5
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 1180005.51
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 11:
If we divide 730 by 77, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 1180005.519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
370 divided by 77 is 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 1180005.5194
Deduct 308 from 370 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1180005.51948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
If we divide 40 by 77, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1180005.51948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
The number 77 fits into 400 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1180005.5194805
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 16:
If we divide 150 by 77, we get 1 and a remainder of 73.
The next digit of our result is 1. 
Result so far: 1180005.51948051
If we subtract 77 from 150, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 1180005.51948051, with a leftover of 7.3e-08.
