Let's divide 351508 by 57
The aim is to understand the frequency of 57 in 351508.

On to step 1:
3 divided by 57 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 57

Advancing to step 2:
57 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 57

Advancing to step 3:
351 divided by 57 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 342 from 351 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 57

Let's proceed to step 4:
57 can be fit into 95 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtracting 57 from 95 leaves us with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 57

Let's proceed to step 5:
380 divided by 57 is 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 616.0
Subtract 342 from 380 to get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 57

Advancing to step 6:
The number 57 fits into 388 6 times, leaving a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 6166.0
If we take 342 away from 388, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
57 can be fit into 460 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6166.8
Subtracting 456 from 460 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 57 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6166.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
If we divide 400 by 57, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 6166.807
Subtract 399 from 400 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
10 divided by 57 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 6166.807
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 57 fits into 100 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 6166.80701
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
If we divide 430 by 57, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 6166.807017
Subtract 399 from 430 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
The number 57 fits into 310 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6166.8070175
If we subtract 285 from 310, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
57 goes into 250 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 6166.80701754
If we subtract 228 from 250, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 6166.80701754, with a leftover of 2.2e-08.
