We're dividing 712237 by 42 
We want to figure out the number of times 712237 can be divided by 42.

Advancing to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 42

Advancing to step 2:
42 goes into 71 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 71 leaves us with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 42

On to step 3:
42 can be fit into 292 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 252 from 292 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 42

Advancing to step 4:
If we divide 402 by 42, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 169.0
Deduct 378 from 402 and we're left with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 42

Step 5:
42 can be fit into 243 5 times, resulting in a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 1695.0
If we subtract 210 from 243, we get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 42

Moving on to step 6:
When dividing 337 by 42, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 16958.0
Subtracting 336 from 337 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
42 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 16958.0
If we take 0 away from 10, 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.

Let's proceed to step 8:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 16958.02
Subtract 84 from 100 to 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.

Moving on to step 9:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 16958.023
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 16958.0238
If we subtract 336 from 340, we 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.

Moving on to step 11:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16958.0238
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.

Step 12:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 16958.023809
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.

Advancing to step 13:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 16958.0238095
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.

Let's proceed to step 14:
If we divide 100 by 42, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 16958.02380952
If we subtract 84 from 100, 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.

Our division results in 16958.02380952 with a remaining 1.6e-08.
