745384 ÷ 42 
We want to figure out the number of times 745384 can be divided by 42.

Advancing to 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
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Step 2:
74 divided by 42 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 32 after subtracting 42 from 74.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 42

Going ahead to step 3:
If we divide 325 by 42, we get 7 and a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 294 from 325 to get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 42

On to step 4:
42 can be fit into 313 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 177.0
Deduct 294 from 313 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 42

Step 5:
The number 42 fits into 198 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 1774.0
The remainder is 30 after subtracting 168 from 198.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 42

On to step 6:
The number 42 fits into 304 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 17747.0
Deduct 294 from 304 and we're left 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.

Going ahead to step 7:
When dividing 100 by 42, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 17747.2
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.

Advancing to step 8:
The number 42 fits into 160 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 17747.23
Deduct 126 from 160 and we're left 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.

Going ahead to step 9:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 17747.238
Subtract 336 from 340 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.

Going ahead to step 10:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 17747.238
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.

Advancing to step 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 17747.23809
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.

Going ahead to step 12:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 17747.238095
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.

On to step 13:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 17747.2380952
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.

Going ahead to step 14:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 17747.23809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 17747.23809523 with a balance of 3.4e-08.
