We're dividing 143687 by 57 
Let's see how many times 57 fits into 143687.

Going ahead to step 1:
1 divided by 57 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 57

Advancing to step 2:
57 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 57

Moving on to step 3:
57 goes into 143 2 times with a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 114 from 143, we get 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 57

On to step 4:
When dividing 296 by 57, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 285 from 296 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 57

Advancing to step 5:
The number 57 fits into 118 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 252.0
Deduct 114 from 118 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 57

Step 6:
57 can be fit into 47 0 times, resulting in a remainder of 47.
The next digit of our result is 0. 
Result so far: 2520.0
The remainder is 47 after subtracting 0 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
If we divide 470 by 57, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 2520.8
If we take 456 away from 470, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 57, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2520.82
Subtracting 114 from 140 leaves us 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.

Step 9:
260 divided by 57 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 2520.824
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.

Moving on to step 10:
57 can be fit into 320 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2520.8245
Subtracting 285 from 320 leaves us 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.

Let's proceed to step 11:
57 goes into 350 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 2520.82456
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 57 fits into 80 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 2520.824561
Subtract 57 from 80 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
57 goes into 230 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 2520.8245614
If we subtract 228 from 230, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
If we divide 20 by 57, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 2520.8245614
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 2520.8245614 and a remainder of 2e-08.
