We look at the division of 804337 by 57 
The aim is to understand the frequency of 57 in 804337.

Going ahead to step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 57

On to step 2:
When dividing 80 by 57, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 23 after subtracting 57 from 80.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 57

Advancing to step 3:
234 divided by 57 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 228 from 234 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 57

On to step 4:
63 divided by 57 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we subtract 57 from 63, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 57

Moving on to step 5:
The number 57 fits into 63 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 1411.0
Deduct 57 from 63 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 57

Going ahead to step 6:
57 goes into 67 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 14111.0
Deduct 57 from 67 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
57 can be fit into 100 1 times, resulting in a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 14111.1
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.

Advancing to step 8:
430 divided by 57 is 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 14111.17
Subtracting 399 from 430 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
The number 57 fits into 310 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 14111.175
Deduct 285 from 310 and we're left 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.

Moving on to step 10:
If we divide 250 by 57, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 14111.1754
If we take 228 away from 250, we end up 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 11:
57 can be fit into 220 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 14111.17543
If we subtract 171 from 220, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
When dividing 490 by 57, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 14111.175438
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
If we divide 340 by 57, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 14111.1754385
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.

Moving on to step 14:
The number 57 fits into 550 9 times, leaving a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 14111.17543859
Deduct 513 from 550 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 14111.17543859 with a remaining 3.7e-08.
