79681888 divided by 625 
The aim is to understand the frequency of 625 in 79681888.

Advancing to step 1:
7 divided by 625 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 625

On to step 2:
625 can be fit into 79 0 times, resulting in a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (6) from the dividend after 79, then repeat: 796 / 625

Going ahead to step 3:
If we divide 796 by 625, we get 1 and a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 625 from 796, we get 171.
Take the next digit (8) from the dividend and append it to 171, then repeat: 1718 / 625

Going ahead to step 4:
625 goes into 1718 2 times with a remainder of 468.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1250 from 1718, we get 468.
Fetch the next digit (1) from the dividend, attach it to 468 and continue: 4681 / 625

Going ahead to step 5:
625 can be fit into 4681 7 times, resulting in a remainder of 306.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtract 4375 from 4681 to get 306.
Take the next digit (8) from the dividend and append it to 306, then repeat: 3068 / 625

Going ahead to step 6:
625 can be fit into 3068 4 times, resulting in a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 1274.0
If we subtract 2500 from 3068, we get 568.
Append the next digit (8) from the dividend to 568 and continue with: 5688 / 625

On to step 7:
625 can be fit into 5688 9 times, resulting in a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 12749.0
Subtract 5625 from 5688 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 625

Moving on to step 8:
When dividing 638 by 625, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 127491.0
Subtract 625 from 638 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
625 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 127491.0
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
When dividing 1300 by 625, we get 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 127491.02
Subtracting 1250 from 1300 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
625 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 127491.02
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
625 goes into 5000 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 127491.0208
Deduct 5000 from 5000 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
0 divided by 625 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 127491.0208
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
The number 625 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 127491.0208
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 127491.0208 with a remaining 0.0.
