We're dividing 669862 by 42 
We want to divide 669862 by 42.

Advancing to step 1:
42 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 42

On to step 2:
42 can be fit into 66 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 66, we end up with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 42

Step 3:
The number 42 fits into 249 5 times, leaving a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 210 away from 249, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 42

Step 4:
42 can be fit into 398 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtracting 378 from 398 leaves us with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 42

Going ahead to step 5:
42 can be fit into 206 4 times, resulting in a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 1594.0
If we take 168 away from 206, we end up with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 42

Step 6:
The number 42 fits into 382 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 15949.0
Deduct 378 from 382 and we're left 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.

Going ahead to step 7:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15949.0
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.

Moving on 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: 15949.09
Deduct 378 from 400 and we're left 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.

Advancing to step 9:
When dividing 220 by 42, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15949.095
Subtract 210 from 220 to 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.

Moving on to step 10:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 15949.0952
The remainder is 16 after subtracting 84 from 100.
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:
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: 15949.09523
If we subtract 126 from 160, we 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.

Moving on to step 12:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 15949.095238
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:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15949.095238
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 14:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 15949.09523809
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 result is 15949.09523809 with a remainder of 2.2e-08.
