Let's divide 71305752 by 421
We want to figure out the number of times 71305752 can be divided by 421.

Moving on to step 1:
421 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 421

Advancing to step 2:
If we divide 71 by 421, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 421

Advancing to step 3:
421 can be fit into 713 1 times, resulting in a remainder of 292.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 421 away from 713, we end up with 292.
Take the next digit (0) from the dividend and append it to 292, then repeat: 2920 / 421

Going ahead to step 4:
2920 divided by 421 is 6 with a remainder of 394.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 2526 from 2920 leaves us with 394.
Append the next digit (5) from the dividend to 394 and continue with: 3945 / 421

On to step 5:
The number 421 fits into 3945 9 times, leaving a remainder of 156.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtract 3789 from 3945 to get 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 421

Advancing to step 6:
421 can be fit into 1567 3 times, resulting in a remainder of 304.
Use 3 as the next digit of our solution. 
Result so far: 1693.0
If we take 1263 away from 1567, we end up with 304.
Grab the next digit (5) from the dividend, add it to 304, then carry on: 3045 / 421

Going ahead to step 7:
When dividing 3045 by 421, we get 7 with a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 16937.0
If we subtract 2947 from 3045, we get 98.
Bring next digit (2) of the dividend behind the 98 and repeat the process: 982 / 421

Going ahead to step 8:
421 can be fit into 982 2 times, resulting in a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 169372.0
Subtracting 842 from 982 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
If we divide 1400 by 421, we get 3 and a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 169372.3
Subtracting 1263 from 1400 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 10:
If we divide 1370 by 421, we get 3 and a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 169372.33
Subtracting 1263 from 1370 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 169372.33 and a remainder of 0.107.
