771145 divided by 57 
The aim is to understand the frequency of 57 in 771145.

On to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the 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

On to step 2:
57 can be fit into 77 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 57 from 77 leaves us with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 57

Let's proceed to step 3:
If we divide 201 by 57, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 171 from 201, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 57

On to step 4:
301 divided by 57 is 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 135.0
Deduct 285 from 301 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 57

Step 5:
When dividing 164 by 57, we get 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 1352.0
Deduct 114 from 164 and we're left with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 57

On to step 6:
The number 57 fits into 505 8 times, leaving a remainder of 49.
The next digit of our result is 8. 
Result so far: 13528.0
Subtracting 456 from 505 leaves us 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.

Going ahead to step 7:
The number 57 fits into 490 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 13528.8
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.

On to step 8:
If we divide 340 by 57, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 13528.85
If we take 285 away from 340, we end up with 55.
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 9:
57 can be fit into 550 9 times, resulting in a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 13528.859
If we take 513 away from 550, we end up 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.

Going ahead to step 10:
57 can be fit into 370 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 13528.8596
Subtracting 342 from 370 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
The number 57 fits into 280 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 13528.85964
If we subtract 228 from 280, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
If we divide 520 by 57, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 13528.859649
Deduct 513 from 520 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
When dividing 70 by 57, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 13528.8596491
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
If we divide 130 by 57, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 13528.85964912
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 13528.85964912 with a remaining 1.6e-08.
