We're dividing 121964 by 42 
Our goal is to divide 121964 by 42.

Moving on to step 1:
42 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.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 42

Advancing to step 2:
12 divided by 42 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 42

Moving on to step 3:
121 divided by 42 is 2 with a remainder of 37.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 37 after subtracting 84 from 121.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 42

Advancing to step 4:
The number 42 fits into 379 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 378 from 379 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 42

On to step 5:
42 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 290.0
If we take 0 away from 16, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 42

Going ahead to step 6:
42 goes into 164 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 2903.0
The remainder is 38 after subtracting 126 from 164.
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 7:
380 divided by 42 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 2903.9
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.

Going ahead to step 8:
When dividing 20 by 42, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2903.9
Subtract 0 from 20 to 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.

Advancing to step 9:
42 goes into 200 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2903.904
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 10:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 2903.9047
Deduct 294 from 320 and we're left 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.

Advancing to step 11:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2903.90476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 42, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 2903.904761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
The number 42 fits into 380 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 2903.9047619
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.

Going ahead to step 14:
42 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2903.9047619
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.

After the division, we end up with 2903.9047619 and a remainder of 2e-08.
