We look at the division of 679039 by 42 
Our goal is to divide 679039 by 42.

On to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 42

Moving on to step 2:
42 goes into 67 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 67 and we're left with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 42

Moving on to step 3:
42 can be fit into 259 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 252 from 259 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 42

Going ahead to step 4:
When dividing 70 by 42, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 161.0
Subtracting 42 from 70 leaves us with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 42

Moving on to step 5:
If we divide 283 by 42, we get 6 and a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 1616.0
Deduct 252 from 283 and we're left with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 42

Going ahead to step 6:
The number 42 fits into 319 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 16167.0
Deduct 294 from 319 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On 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: 16167.5
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.

Advancing to step 8:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 16167.59
Subtracting 378 from 400 leaves us 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.

Moving on to step 9:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 16167.595
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 42, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 16167.5952
If we take 84 away from 100, we end up 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.

On to 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: 16167.59523
Subtracting 126 from 160 leaves us 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:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 16167.595238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16167.595238
If we subtract 0 from 40, we 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.

On to step 14:
When dividing 400 by 42, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 16167.59523809
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.

The final outcome is 16167.59523809, with a leftover of 2.2e-08.
