58123970 divided by 778 
The aim is to understand the frequency of 778 in 58123970.

Advancing to step 1:
The number 778 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 778

Let's proceed to step 2:
If we divide 58 by 778, we get 0 and a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 778

On to step 3:
581 divided by 778 is 0 with a remainder of 581.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 581, we get 581.
Include the next digit (2) from the dividend after 581, then repeat: 5812 / 778

Going ahead to step 4:
778 goes into 5812 7 times with a remainder of 366.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5446 from 5812 and we're left with 366.
Take the next digit (3) from the dividend and append it to 366, then repeat: 3663 / 778

Moving on to step 5:
The number 778 fits into 3663 4 times, leaving a remainder of 551.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 551 after subtracting 3112 from 3663.
Bring next digit (9) of the dividend behind the 551 and repeat the process: 5519 / 778

Advancing to step 6:
When dividing 5519 by 778, we get 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 747.0
Subtract 5446 from 5519 to get 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 778

Let's proceed to step 7:
The number 778 fits into 737 0 times, leaving a remainder of 737.
The number 0 becomes the next digit in our result. 
Result so far: 7470.0
The remainder is 737 after subtracting 0 from 737.
Append the next digit (0) from the dividend to 737 and continue with: 7370 / 778

Going ahead to step 8:
778 goes into 7370 9 times with a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 74709.0
If we take 7002 away from 7370, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 9:
When dividing 3680 by 778, we get 4 with a remainder of 568.
Record the quotient 4 as the next digit in the result. 
Result so far: 74709.4
If we take 3112 away from 3680, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 10:
778 can be fit into 5680 7 times, resulting in a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 74709.47
Subtract 5446 from 5680 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 11:
778 goes into 2340 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 74709.473
Subtracting 2334 from 2340 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
778 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 74709.473
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
778 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 74709.473
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 74709.473 and a remainder of 0.0006.
