Let's divide 745294 by 42
Let's see how many times 42 fits into 745294.

On to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 42

On to step 2:
74 divided by 42 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 74 leaves us with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 42

Let's proceed to step 3:
When dividing 325 by 42, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 294 away from 325, we end up with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 42

Let's proceed to step 4:
312 divided by 42 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
The remainder is 18 after subtracting 294 from 312.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 42

Moving on to step 5:
If we divide 189 by 42, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 1774.0
If we subtract 168 from 189, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 42

On to step 6:
42 can be fit into 214 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 17745.0
Subtract 210 from 214 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 7:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 17745.0
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.

Going ahead to step 8:
42 goes into 400 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 17745.09
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.

Moving on to step 9:
220 divided by 42 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 17745.095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 17745.0952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 17745.09523
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 12:
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: 17745.095238
If we take 336 away from 340, we end up 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.

Step 13:
40 divided by 42 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 17745.095238
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.

Moving on to step 14:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 17745.09523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 17745.09523809, with a leftover of 2.2e-08.
