742370 divided by 42 
We want to divide 742370 by 42.

Step 1:
7 divided by 42 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 42

Going ahead to step 2:
If we divide 74 by 42, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 32 after subtracting 42 from 74.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 42

Step 3:
When dividing 322 by 42, we get 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 294 from 322, we get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 42

Step 4:
42 goes into 283 6 times with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 176.0
If we subtract 252 from 283, we get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 42

On to step 5:
42 goes into 317 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 1767.0
Subtracting 294 from 317 leaves us with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 42

Advancing to step 6:
42 goes into 230 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 17675.0
Subtracting 210 from 230 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.

Moving on to step 7:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 17675.4
Subtract 168 from 200 to 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.

On to step 8:
If we divide 320 by 42, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 17675.47
Subtracting 294 from 320 leaves us 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:
If we divide 260 by 42, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 17675.476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 17675.4761
Subtract 42 from 80 to 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.

Going ahead to step 11:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 17675.47619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
20 divided by 42 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17675.47619
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.

Let's proceed to step 13:
When dividing 200 by 42, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 17675.4761904
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.

Step 14:
When dividing 320 by 42, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 17675.47619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 17675.47619047, with a leftover of 2.6e-08.
