We're dividing 122988 by 57 
Our goal is to divide 122988 by 57.

On to step 1:
57 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 57

Step 2:
57 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 57

On to step 3:
If we divide 122 by 57, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 114 from 122 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 57

Step 4:
89 divided by 57 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 57 from 89 leaves us with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 57

Moving on to step 5:
When dividing 328 by 57, we get 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
If we subtract 285 from 328, we get 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 57

On to step 6:
If we divide 438 by 57, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 2157.0
If we take 399 away from 438, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
57 goes into 390 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 2157.6
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 57 fits into 480 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2157.68
If we take 456 away from 480, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 57, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 2157.684
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 57 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2157.6842
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
The number 57 fits into 60 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 2157.68421
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
57 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 2157.68421
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
57 goes into 300 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2157.6842105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
If we divide 150 by 57, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2157.68421052
If we subtract 114 from 150, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 2157.68421052 and a remainder of 3.6e-08.
