We look at the division of 312091 by 57 
Let's see how many times 57 fits into 312091.

Moving on to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 57

Step 2:
31 divided by 57 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 57

Let's proceed to step 3:
If we divide 312 by 57, we get 5 and a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 27 after subtracting 285 from 312.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 57

Let's proceed to step 4:
270 divided by 57 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 228 from 270 to get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 57

Going ahead to step 5:
The number 57 fits into 429 7 times, leaving a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 547.0
If we take 399 away from 429, we end up with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 57

Going ahead to step 6:
57 can be fit into 301 5 times, resulting in a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 5475.0
If we take 285 away from 301, we end up 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.

Going ahead to step 7:
When dividing 160 by 57, we get 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 5475.2
The remainder is 46 after subtracting 114 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
57 can be fit into 460 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 5475.28
If we take 456 away from 460, we end up 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.

Advancing to step 9:
When dividing 40 by 57, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5475.28
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 57, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 5475.2807
Deduct 399 from 400 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
57 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5475.2807
Deduct 0 from 10 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 12:
57 can be fit into 100 1 times, resulting in a remainder of 43.
The next digit of our result is 1. 
Result so far: 5475.280701
Subtracting 57 from 100 leaves us 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.

On to step 13:
430 divided by 57 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 5475.2807017
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.

Going ahead to step 14:
If we divide 310 by 57, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5475.28070175
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.

After the division, we end up with 5475.28070175 and a remainder of 2.5e-08.
