We divide 850910 by 57
The aim is to understand the frequency of 57 in 850910.

Moving on to step 1:
If we divide 8 by 57, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 57

Step 2:
57 can be fit into 85 1 times, resulting in a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 57 from 85, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 57

On to step 3:
The number 57 fits into 280 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 228 from 280 and we're left with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 57

Advancing to step 4:
57 goes into 529 9 times with a remainder of 16.
The next digit of our result is 9. 
Result so far: 149.0
If we subtract 513 from 529, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 57

Advancing to step 5:
161 divided by 57 is 2 with a remainder of 47.
Record the quotient 2 as the next digit in the result. 
Result so far: 1492.0
Subtract 114 from 161 to get 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 57

Going ahead to step 6:
The number 57 fits into 470 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 14928.0
Subtract 456 from 470 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 57, we get 2 and a remainder of 26.
The next digit of our result is 2. 
Result so far: 14928.2
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
When dividing 260 by 57, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 14928.24
Subtract 228 from 260 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
If we divide 320 by 57, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 14928.245
If we take 285 away from 320, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
When dividing 350 by 57, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 14928.2456
Subtract 342 from 350 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
57 goes into 80 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 14928.24561
Deduct 57 from 80 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
57 goes into 230 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14928.245614
Subtracting 228 from 230 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 57, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14928.245614
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
When dividing 200 by 57, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 14928.24561403
Subtracting 171 from 200 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 14928.24561403, with a leftover of 2.9e-08.
