Let's divide 120143 by 63
We want to figure out the number of times 120143 can be divided by 63.

On to step 1:
63 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 63

Advancing to step 2:
63 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 63

Advancing to step 3:
120 divided by 63 is 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 57 after subtracting 63 from 120.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 63

On to step 4:
The number 63 fits into 571 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 567 from 571 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 63

Going ahead to step 5:
When dividing 44 by 63, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
The remainder is 44 after subtracting 0 from 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 63

Advancing to step 6:
63 goes into 443 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1907.0
If we subtract 441 from 443, 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 7:
If we divide 20 by 63, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1907.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 63, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 1907.03
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
63 can be fit into 110 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1907.031
Subtracting 63 from 110 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
If we divide 470 by 63, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 1907.0317
Deduct 441 from 470 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
The number 63 fits into 290 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 1907.03174
If we subtract 252 from 290, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
63 can be fit into 380 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1907.031746
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
When dividing 20 by 63, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1907.031746
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.

On to step 14:
If we divide 200 by 63, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 1907.03174603
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 1907.03174603 with a remaining 1.1e-08.
