71063132 divided by 420 
Our goal is to divide 71063132 by 420.

Step 1:
420 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 420

Going ahead to step 2:
When dividing 71 by 420, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 420

Going ahead to step 3:
The number 420 fits into 710 1 times, leaving a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 420 from 710 to get 290.
Append the next digit (6) from the dividend to 290 and continue with: 2906 / 420

Advancing to step 4:
If we divide 2906 by 420, we get 6 and a remainder of 386.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2520 from 2906, we get 386.
Fetch the next digit (3) from the dividend, attach it to 386 and continue: 3863 / 420

Advancing to step 5:
3863 divided by 420 is 9 with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
If we take 3780 away from 3863, we end up with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 420

Going ahead to step 6:
If we divide 831 by 420, we get 1 and a remainder of 411.
The number 1 becomes the next digit in our result. 
Result so far: 1691.0
Deduct 420 from 831 and we're left with 411.
Bring next digit (3) of the dividend behind the 411 and repeat the process: 4113 / 420

On to step 7:
420 can be fit into 4113 9 times, resulting in a remainder of 333.
Record the quotient 9 as the next digit in the result. 
Result so far: 16919.0
Deduct 3780 from 4113 and we're left with 333.
Take the next digit (2) from the dividend and append it to 333, then repeat: 3332 / 420

On to step 8:
3332 divided by 420 is 7 with a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 169197.0
If we subtract 2940 from 3332, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 9:
420 goes into 3920 9 times with a remainder of 140.
Write down 9 as next digit of the result. 
Result so far: 169197.9
The remainder is 140 after subtracting 3780 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
420 goes into 1400 3 times with a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 169197.93
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
The number 420 fits into 1400 3 times, leaving a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 169197.933
Subtract 1260 from 1400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 169197.933 with a remaining 0.014.
