Let's divide 71487727 by 421
We want to figure out the number of times 71487727 can be divided by 421.

Advancing to step 1:
When dividing 7 by 421, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 421

Advancing to step 2:
421 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 421

Let's proceed to step 3:
421 goes into 714 1 times with a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 293 after subtracting 421 from 714.
Fetch the next digit (8) from the dividend, attach it to 293 and continue: 2938 / 421

Moving on to step 4:
The number 421 fits into 2938 6 times, leaving a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 412 after subtracting 2526 from 2938.
Take the next digit (7) from the dividend and append it to 412, then repeat: 4127 / 421

Moving on to step 5:
If we divide 4127 by 421, we get 9 and a remainder of 338.
Put 9 as the next digit of the answer. 
Result so far: 169.0
The remainder is 338 after subtracting 3789 from 4127.
Include the next digit (7) from the dividend after 338, then repeat: 3387 / 421

Going ahead to step 6:
When dividing 3387 by 421, we get 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 1698.0
If we subtract 3368 from 3387, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 421

Let's proceed to step 7:
The number 421 fits into 192 0 times, leaving a remainder of 192.
Write down 0 as next digit of the result. 
Result so far: 16980.0
The remainder is 192 after subtracting 0 from 192.
Take the next digit (7) from the dividend and append it to 192, then repeat: 1927 / 421

Step 8:
1927 divided by 421 is 4 with a remainder of 243.
Use 4 as the next digit of our solution. 
Result so far: 169804.0
Subtract 1684 from 1927 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 9:
If we divide 2430 by 421, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 169804.5
Subtract 2105 from 2430 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 10:
421 goes into 3250 7 times with a remainder of 303.
Write down 7 as next digit of the result. 
Result so far: 169804.57
Subtract 2947 from 3250 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 11:
If we divide 3030 by 421, we get 7 and a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 169804.577
Deduct 2947 from 3030 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final outcome is 169804.577, with a leftover of 0.0083.
