121140 ÷ 57 
We're looking to find how many times 57 goes into 121140.

On to step 1:
57 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 57

Step 2:
When dividing 12 by 57, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 57

Going ahead to step 3:
The number 57 fits into 121 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 114 from 121 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 57

Step 4:
The number 57 fits into 71 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 14 after subtracting 57 from 71.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 57

Step 5:
The number 57 fits into 144 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 212.0
If we subtract 114 from 144, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 57

On to step 6:
300 divided by 57 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2125.0
Deduct 285 from 300 and we're left 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.

Let's proceed to step 7:
When dividing 150 by 57, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2125.2
The remainder is 36 after subtracting 114 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 57, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 2125.26
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
57 goes into 180 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 2125.263
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
90 divided by 57 is 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 2125.2631
The remainder is 33 after subtracting 57 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 11:
57 can be fit into 330 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 2125.26315
If we subtract 285 from 330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
If we divide 450 by 57, we get 7 and a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 2125.263157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
If we divide 510 by 57, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 2125.2631578
Deduct 456 from 510 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
540 divided by 57 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 2125.26315789
Deduct 513 from 540 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 2125.26315789 with a remaining 2.7e-08.
