We look at the division of 743168 by 42 
We want to divide 743168 by 42.

On to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 42

Moving on to step 2:
74 divided by 42 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 74 and we're left with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 42

Step 3:
42 can be fit into 323 7 times, resulting in a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 294 away from 323, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 42

Going ahead to step 4:
The number 42 fits into 291 6 times, leaving a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 176.0
Subtract 252 from 291 to get 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 42

On to step 5:
42 goes into 396 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 1769.0
Deduct 378 from 396 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 42

Advancing to step 6:
When dividing 188 by 42, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 17694.0
Subtracting 168 from 188 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 42 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 17694.4
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 17694.47
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 17694.476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 17694.4761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 17694.47619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17694.47619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 17694.4761904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 17694.47619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 17694.47619047, and the remainder is 2.6e-08.
