Let's divide 775944 by 57
The aim is to understand the frequency of 57 in 775944.

On to step 1:
The number 57 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 57

Moving on to step 2:
57 can be fit into 77 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 57 from 77 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 57

Moving on to step 3:
205 divided by 57 is 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 171 from 205 and we're left with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 57

Moving on to step 4:
The number 57 fits into 349 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 342 from 349, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 57

Advancing to step 5:
When dividing 74 by 57, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1361.0
The remainder is 17 after subtracting 57 from 74.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 57

On to step 6:
57 goes into 174 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13613.0
Deduct 171 from 174 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
57 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13613.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
57 can be fit into 300 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13613.05
If we subtract 285 from 300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 13613.052
Subtract 114 from 150 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
If we divide 360 by 57, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 13613.0526
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
When dividing 180 by 57, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 13613.05263
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
If we divide 90 by 57, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 13613.052631
If we subtract 57 from 90, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
57 can be fit into 330 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 13613.0526315
Deduct 285 from 330 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
57 goes into 450 7 times with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 13613.05263157
Subtracting 399 from 450 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 13613.05263157, with a leftover of 5.1e-08.
