Let's divide 40821348 by 421
Let's see how many times 421 fits into 40821348.

Let's proceed to step 1:
The number 421 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 421

Going ahead to step 2:
40 divided by 421 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 421

Advancing to step 3:
If we divide 408 by 421, we get 0 and a remainder of 408.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 408 leaves us with 408.
Bring next digit (2) of the dividend behind the 408 and repeat the process: 4082 / 421

Let's proceed to step 4:
421 can be fit into 4082 9 times, resulting in a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 3789 from 4082 leaves us with 293.
Bring next digit (1) of the dividend behind the 293 and repeat the process: 2931 / 421

Moving on to step 5:
421 can be fit into 2931 6 times, resulting in a remainder of 405.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 2526 from 2931 and we're left with 405.
Include the next digit (3) from the dividend after 405, then repeat: 4053 / 421

Step 6:
421 can be fit into 4053 9 times, resulting in a remainder of 264.
The next digit of our result is 9. 
Result so far: 969.0
Subtract 3789 from 4053 to get 264.
Take the next digit (4) from the dividend and append it to 264, then repeat: 2644 / 421

On to step 7:
2644 divided by 421 is 6 with a remainder of 118.
Put 6 as the next digit of the answer. 
Result so far: 9696.0
If we take 2526 away from 2644, we end up with 118.
Grab the next digit (8) from the dividend, add it to 118, then carry on: 1188 / 421

Step 8:
When dividing 1188 by 421, we get 2 with a remainder of 346.
Write down 2 as next digit of the result. 
Result so far: 96962.0
Deduct 842 from 1188 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 9:
3460 divided by 421 is 8 with a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 96962.8
Subtracting 3368 from 3460 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
920 divided by 421 is 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 96962.82
Subtract 842 from 920 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
When dividing 780 by 421, we get 1 with a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 96962.821
The remainder is 359 after subtracting 421 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 12:
When dividing 3590 by 421, we get 8 with a remainder of 222.
The next digit of our result is 8. 
Result so far: 96962.8218
Subtracting 3368 from 3590 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 13:
421 can be fit into 2220 5 times, resulting in a remainder of 115.
The next digit of our result is 5. 
Result so far: 96962.82185
The remainder is 115 after subtracting 2105 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 14:
1150 divided by 421 is 2 with a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 96962.821852
The remainder is 308 after subtracting 842 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 15:
If we divide 3080 by 421, we get 7 and a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 96962.8218527
Subtract 2947 from 3080 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 16:
The number 421 fits into 1330 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 96962.82185273
If we subtract 1263 from 1330, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 96962.82185273 and a remainder of 6.7e-08.
