We look at the division of 42213170 by 427 
We want to figure out the number of times 42213170 can be divided by 427.

On to step 1:
If we divide 4 by 427, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 427

Going ahead to step 2:
The number 427 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 427

Moving on to step 3:
422 divided by 427 is 0 with a remainder of 422.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 422, we end up with 422.
Grab the next digit (1) from the dividend, add it to 422, then carry on: 4221 / 427

On to step 4:
427 goes into 4221 9 times with a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 3843 from 4221 leaves us with 378.
Include the next digit (3) from the dividend after 378, then repeat: 3783 / 427

Going ahead to step 5:
427 can be fit into 3783 8 times, resulting in a remainder of 367.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 3416 from 3783, we get 367.
Bring next digit (1) of the dividend behind the 367 and repeat the process: 3671 / 427

Moving on to step 6:
When dividing 3671 by 427, we get 8 with a remainder of 255.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
Subtracting 3416 from 3671 leaves us with 255.
Bring next digit (7) of the dividend behind the 255 and repeat the process: 2557 / 427

Advancing to step 7:
When dividing 2557 by 427, we get 5 with a remainder of 422.
Write down 5 as next digit of the result. 
Result so far: 9885.0
Deduct 2135 from 2557 and we're left with 422.
Bring next digit (0) of the dividend behind the 422 and repeat the process: 4220 / 427

On to step 8:
The number 427 fits into 4220 9 times, leaving a remainder of 377.
Use 9 as the next digit of our solution. 
Result so far: 98859.0
If we take 3843 away from 4220, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 9:
3770 divided by 427 is 8 with a remainder of 354.
Write down 8 as next digit of the result. 
Result so far: 98859.8
If we take 3416 away from 3770, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
When dividing 3540 by 427, we get 8 with a remainder of 124.
The next digit of our result is 8. 
Result so far: 98859.88
Deduct 3416 from 3540 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 98859.88 and a remainder of 0.124.
