We look at the division of 891204 by 42 
We want to divide 891204 by 42.

Advancing to step 1:
8 divided by 42 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 42

Let's proceed to step 2:
42 goes into 89 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 5 after subtracting 84 from 89.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 42

Going ahead to step 3:
If we divide 51 by 42, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 42 away from 51, we end up with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 42

Step 4:
When dividing 92 by 42, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 212.0
The remainder is 8 after subtracting 84 from 92.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 42

Moving on to step 5:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 2121.0
Deduct 42 from 80 and we're left with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 42

Step 6:
The number 42 fits into 384 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 21219.0
Subtract 378 from 384 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
42 goes into 60 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 21219.1
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 21219.14
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
42 goes into 120 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 21219.142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 21219.1428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 21219.14285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 21219.142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 21219.1428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 21219.14285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 21219.14285714 and a remainder of 1.2e-08.
