Let's divide 917983 by 42
We're looking to find how many times 42 goes into 917983.

Advancing to step 1:
9 divided by 42 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 42

On to step 2:
If we divide 91 by 42, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 84 from 91 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 42

Advancing to step 3:
If we divide 77 by 42, we get 1 and a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 35 after subtracting 42 from 77.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 42

Let's proceed to step 4:
The number 42 fits into 359 8 times, leaving a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 218.0
If we subtract 336 from 359, we get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 42

Let's proceed to step 5:
If we divide 238 by 42, we get 5 and a remainder of 28.
The next digit of our result is 5. 
Result so far: 2185.0
If we subtract 210 from 238, we get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 42

Advancing to step 6:
42 goes into 283 6 times with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 21856.0
Subtracting 252 from 283 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
42 goes into 310 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 21856.7
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 42 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 21856.73
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
When dividing 340 by 42, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 21856.738
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 21856.738
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 21856.73809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 21856.738095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
42 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 21856.7380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 21856.73809523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 21856.73809523, with a leftover of 3.4e-08.
