We're dividing 956991 by 42 
We want to divide 956991 by 42.

Step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 42

On to step 2:
95 divided by 42 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 84 from 95 leaves us with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 42

Going ahead to step 3:
If we divide 116 by 42, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 32 after subtracting 84 from 116.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 42

Step 4:
If we divide 329 by 42, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 227.0
If we subtract 294 from 329, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 42

Advancing to step 5:
42 can be fit into 359 8 times, resulting in a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 2278.0
If we subtract 336 from 359, we get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 42

Moving on to step 6:
231 divided by 42 is 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 22785.0
Deduct 210 from 231 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 42 fits into 210 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 22785.5
If we take 210 away from 210, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 42, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22785.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 42 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22785.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 22785.5 with a remaining 0.0.
