82639644 ÷ 421 
Let's see how many times 421 fits into 82639644.

Let's proceed to step 1:
When dividing 8 by 421, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 421

Advancing to step 2:
421 goes into 82 0 times with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Fetch the next digit (6) from the dividend, attach it to 82 and continue: 826 / 421

Going ahead to step 3:
When dividing 826 by 421, we get 1 with a remainder of 405.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 421 away from 826, we end up with 405.
Append the next digit (3) from the dividend to 405 and continue with: 4053 / 421

Let's proceed to step 4:
The number 421 fits into 4053 9 times, leaving a remainder of 264.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 264 after subtracting 3789 from 4053.
Grab the next digit (9) from the dividend, add it to 264, then carry on: 2649 / 421

On to step 5:
2649 divided by 421 is 6 with a remainder of 123.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtracting 2526 from 2649 leaves us with 123.
Fetch the next digit (6) from the dividend, attach it to 123 and continue: 1236 / 421

Step 6:
The number 421 fits into 1236 2 times, leaving a remainder of 394.
Write down 2 as next digit of the result. 
Result so far: 1962.0
If we subtract 842 from 1236, we get 394.
Include the next digit (4) from the dividend after 394, then repeat: 3944 / 421

Let's proceed to step 7:
421 can be fit into 3944 9 times, resulting in a remainder of 155.
Write down 9 as next digit of the result. 
Result so far: 19629.0
Subtract 3789 from 3944 to get 155.
Take the next digit (4) from the dividend and append it to 155, then repeat: 1554 / 421

Advancing to step 8:
1554 divided by 421 is 3 with a remainder of 291.
Write down 3 as next digit of the result. 
Result so far: 196293.0
Deduct 1263 from 1554 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 9:
2910 divided by 421 is 6 with a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 196293.6
If we take 2526 away from 2910, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 10:
When dividing 3840 by 421, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 196293.69
Subtracting 3789 from 3840 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
510 divided by 421 is 1 with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 196293.691
Subtracting 421 from 510 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 12:
421 can be fit into 890 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 196293.6912
If we take 842 away from 890, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
480 divided by 421 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 196293.69121
Deduct 421 from 480 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 14:
421 can be fit into 590 1 times, resulting in a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 196293.691211
If we take 421 away from 590, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The quotient of the division is 196293.691211, and the remainder is 1.69e-05.
