Let's divide 120320 by 42
We want to divide 120320 by 42.

Let's proceed to step 1:
1 divided by 42 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 42

On to step 2:
12 divided by 42 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 42

Going ahead to step 3:
When dividing 120 by 42, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 84 from 120 and we're left with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 42

On to step 4:
When dividing 363 by 42, we get 8 with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 27 after subtracting 336 from 363.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 42

Moving on to step 5:
If we divide 272 by 42, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
If we take 252 away from 272, we end up with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 42

Let's proceed to step 6:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 2864.0
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
42 goes into 320 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 2864.7
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 2864.76
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 2864.761
Subtract 42 from 80 to 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.

Let's proceed to step 10:
380 divided by 42 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 2864.7619
Subtracting 378 from 380 leaves us 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.

Advancing to step 11:
If we divide 20 by 42, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2864.7619
The remainder is 20 after subtracting 0 from 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 12:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 2864.761904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
42 goes into 320 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 2864.7619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
42 goes into 260 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 2864.76190476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 2864.76190476 with a remaining 8e-09.
