We're dividing 847408 by 42 
We want to figure out the number of times 847408 can be divided by 42.

Moving on to step 1:
42 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 42

Going ahead to step 2:
84 divided by 42 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 84 from 84 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 42

Going ahead to step 3:
When dividing 7 by 42, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Going ahead to step 4:
42 can be fit into 74 1 times, resulting in a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Subtracting 42 from 74 leaves us with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 42

On to step 5:
320 divided by 42 is 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 2017.0
If we take 294 away from 320, we end up with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 42

Let's proceed to step 6:
If we divide 268 by 42, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 20176.0
If we subtract 252 from 268, we get 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 7:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 20176.3
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 8:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 20176.38
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 42, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 20176.38
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 10:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 20176.3809
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.

Going ahead to step 11:
If we divide 220 by 42, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 20176.38095
Subtracting 210 from 220 leaves us 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.

Moving on to step 12:
When dividing 100 by 42, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 20176.380952
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.

Going ahead to step 13:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 20176.3809523
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.

Step 14:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 20176.38095238
Deduct 336 from 340 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.

The final outcome is 20176.38095238, with a leftover of 4e-09.
