We look at the division of 17907407 by 821 
We're looking to find how many times 821 goes into 17907407.

Moving on to step 1:
821 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 821

Moving on to step 2:
The number 821 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 821

Step 3:
179 divided by 821 is 0 with a remainder of 179.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 179 leaves us with 179.
Fetch the next digit (0) from the dividend, attach it to 179 and continue: 1790 / 821

On to step 4:
The number 821 fits into 1790 2 times, leaving a remainder of 148.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1642 from 1790 and we're left with 148.
Fetch the next digit (7) from the dividend, attach it to 148 and continue: 1487 / 821

Advancing to step 5:
If we divide 1487 by 821, we get 1 and a remainder of 666.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 666 after subtracting 821 from 1487.
Bring next digit (4) of the dividend behind the 666 and repeat the process: 6664 / 821

On to step 6:
The number 821 fits into 6664 8 times, leaving a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
The remainder is 96 after subtracting 6568 from 6664.
Bring next digit (0) of the dividend behind the 96 and repeat the process: 960 / 821

Moving on to step 7:
821 goes into 960 1 times with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 2181.0
If we subtract 821 from 960, we get 139.
Bring next digit (7) of the dividend behind the 139 and repeat the process: 1397 / 821

Moving on to step 8:
If we divide 1397 by 821, we get 1 and a remainder of 576.
The number 1 becomes the next digit in our result. 
Result so far: 21811.0
Subtract 821 from 1397 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 9:
When dividing 5760 by 821, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 21811.7
Deduct 5747 from 5760 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
821 goes into 130 0 times with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 21811.7
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
If we divide 1300 by 821, we get 1 and a remainder of 479.
Put 1 as the next digit of the answer. 
Result so far: 21811.701
Subtract 821 from 1300 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 12:
821 can be fit into 4790 5 times, resulting in a remainder of 685.
The next digit of our result is 5. 
Result so far: 21811.7015
The remainder is 685 after subtracting 4105 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 13:
The number 821 fits into 6850 8 times, leaving a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 21811.70158
Deduct 6568 from 6850 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 14:
821 goes into 2820 3 times with a remainder of 357.
Put 3 as the next digit of the answer. 
Result so far: 21811.701583
Deduct 2463 from 2820 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 15:
The number 821 fits into 3570 4 times, leaving a remainder of 286.
Put 4 as the next digit of the answer. 
Result so far: 21811.7015834
The remainder is 286 after subtracting 3284 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 16:
When dividing 2860 by 821, we get 3 with a remainder of 397.
The next digit of our result is 3. 
Result so far: 21811.70158343
Subtracting 2463 from 2860 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

The quotient of the division is 21811.70158343, and the remainder is 3.97e-07.
