990679 divided by 42 
We want to divide 990679 by 42.

Advancing to step 1:
42 goes into 9 0 times 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.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 42

Let's proceed to step 2:
99 divided by 42 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 15 after subtracting 84 from 99.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 42

Let's proceed to step 3:
150 divided by 42 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 126 from 150 leaves us with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 42

On to step 4:
If we divide 246 by 42, we get 5 and a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 235.0
If we take 210 away from 246, we end up with 36.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 42

Advancing to step 5:
367 divided by 42 is 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 2358.0
If we take 336 away from 367, we end up with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 42

Let's proceed to step 6:
When dividing 319 by 42, we get 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 23587.0
If we subtract 294 from 319, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
42 goes into 250 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 23587.5
Subtract 210 from 250 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 42 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 23587.59
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 23587.595
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.

Step 10:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 23587.5952
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.

Step 11:
160 divided by 42 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 23587.59523
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 12:
When dividing 340 by 42, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 23587.595238
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.

On to step 13:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 23587.595238
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.

Step 14:
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: 23587.59523809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 23587.59523809, with a leftover of 2.2e-08.
