We're dividing 721102 by 42 
We're looking to find how many times 42 goes into 721102.

Advancing to step 1:
7 divided by 42 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

Let's proceed to step 2:
When dividing 72 by 42, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 42 away from 72, we end up with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 42

Step 3:
301 divided by 42 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 294 from 301, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 42

Advancing to step 4:
42 can be fit into 71 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 171.0
The remainder is 29 after subtracting 42 from 71.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 42

Moving on to step 5:
When dividing 290 by 42, we get 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 1716.0
Subtract 252 from 290 to get 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 42

Going ahead to step 6:
When dividing 382 by 42, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 17169.0
The remainder is 4 after subtracting 378 from 382.
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:
When dividing 40 by 42, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 17169.0
If we take 0 away from 40, we end up 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.

Going ahead to step 8:
400 divided by 42 is 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 17169.09
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.

Going ahead to step 9:
220 divided by 42 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17169.095
If we take 210 away from 220, we end up 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.

Step 10:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 17169.0952
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.

Going ahead to step 11:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 17169.09523
If we take 126 away from 160, we end up 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.

Moving on to step 12:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 17169.095238
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.

Moving on to step 13:
42 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 17169.095238
The remainder is 40 after subtracting 0 from 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 14:
42 goes into 400 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 17169.09523809
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.

In conclusion, the division gives 17169.09523809 with a balance of 2.2e-08.
