We look at the division of 952171 by 57 
The aim is to understand the frequency of 57 in 952171.

On to step 1:
When dividing 9 by 57, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 57

Step 2:
57 goes into 95 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 57 from 95 leaves us with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 57

Moving on to step 3:
382 divided by 57 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 342 from 382 leaves us with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 57

Advancing to step 4:
When dividing 401 by 57, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 399 from 401, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 57

On to step 5:
The number 57 fits into 27 0 times, leaving a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 1670.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 57

Let's proceed to step 6:
57 goes into 271 4 times with a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 16704.0
Deduct 228 from 271 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
If we divide 430 by 57, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 16704.7
The remainder is 31 after subtracting 399 from 430.
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 8:
The number 57 fits into 310 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16704.75
Subtracting 285 from 310 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
57 can be fit into 250 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 16704.754
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
220 divided by 57 is 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 16704.7543
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
57 can be fit into 490 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 16704.75438
Deduct 456 from 490 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
The number 57 fits into 340 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 16704.754385
The remainder is 55 after subtracting 285 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
57 can be fit into 550 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 16704.7543859
Subtract 513 from 550 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.

Let's proceed to step 14:
If we divide 370 by 57, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 16704.75438596
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 16704.75438596 and a remainder of 2.8e-08.
