750420 divided by 42 
We want to figure out the number of times 750420 can be divided by 42.

On to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 42

Moving on to step 2:
The number 42 fits into 75 1 times, leaving a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 42 from 75 and we're left with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 42

Moving on to step 3:
42 goes into 330 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 294 from 330 to get 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 42

Advancing to step 4:
364 divided by 42 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtract 336 from 364 to get 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 42

Advancing to step 5:
If we divide 282 by 42, we get 6 and a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 1786.0
Subtracting 252 from 282 leaves us with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 42

Step 6:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17867.0
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 17867.1
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 42, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17867.14
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
42 goes into 120 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 17867.142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 17867.1428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 17867.14285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 17867.142857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 17867.1428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 17867.14285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 17867.14285714 and a remainder of 1.2e-08.
