40250953 ÷ 821 
We want to divide 40250953 by 821.

Advancing to step 1:
When dividing 4 by 821, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 821

Let's proceed to step 2:
If we divide 40 by 821, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 821

Moving on to step 3:
The number 821 fits into 402 0 times, leaving a remainder of 402.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 402 to get 402.
Fetch the next digit (5) from the dividend, attach it to 402 and continue: 4025 / 821

Moving on to step 4:
The number 821 fits into 4025 4 times, leaving a remainder of 741.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 3284 from 4025, we get 741.
Include the next digit (0) from the dividend after 741, then repeat: 7410 / 821

Going ahead to step 5:
821 can be fit into 7410 9 times, resulting in a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 7389 away from 7410, we end up with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 821

Going ahead to step 6:
The number 821 fits into 219 0 times, leaving a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
The remainder is 219 after subtracting 0 from 219.
Fetch the next digit (5) from the dividend, attach it to 219 and continue: 2195 / 821

Going ahead to step 7:
When dividing 2195 by 821, we get 2 with a remainder of 553.
Put 2 as the next digit of the answer. 
Result so far: 4902.0
If we subtract 1642 from 2195, we get 553.
Take the next digit (3) from the dividend and append it to 553, then repeat: 5533 / 821

Let's proceed to step 8:
821 goes into 5533 6 times with a remainder of 607.
The next digit of our result is 6. 
Result so far: 49026.0
Subtracting 4926 from 5533 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Let's proceed to step 9:
821 can be fit into 6070 7 times, resulting in a remainder of 323.
Write down 7 as next digit of the result. 
Result so far: 49026.7
If we subtract 5747 from 6070, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 10:
When dividing 3230 by 821, we get 3 with a remainder of 767.
Write down 3 as next digit of the result. 
Result so far: 49026.73
Subtracting 2463 from 3230 leaves us with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Moving on to step 11:
821 goes into 7670 9 times with a remainder of 281.
The next digit of our result is 9. 
Result so far: 49026.739
The remainder is 281 after subtracting 7389 from 7670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 12:
If we divide 2810 by 821, we get 3 and a remainder of 347.
Use 3 as the next digit of our solution. 
Result so far: 49026.7393
If we take 2463 away from 2810, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 13:
821 can be fit into 3470 4 times, resulting in a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 49026.73934
Subtracting 3284 from 3470 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 14:
The number 821 fits into 1860 2 times, leaving a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 49026.739342
The remainder is 218 after subtracting 1642 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
When dividing 2180 by 821, we get 2 with a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 49026.7393422
If we subtract 1642 from 2180, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 49026.7393422, and the remainder is 5.38e-06.
