We look at the division of 8090946 by 521 
We're looking to find how many times 521 goes into 8090946.

Let's proceed to step 1:
When dividing 8 by 521, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 521

On to step 2:
521 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 521

On to step 3:
The number 521 fits into 809 1 times, leaving a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 521 from 809 to get 288.
Grab the next digit (0) from the dividend, add it to 288, then carry on: 2880 / 521

Advancing to step 4:
The number 521 fits into 2880 5 times, leaving a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2605 from 2880 to get 275.
Fetch the next digit (9) from the dividend, attach it to 275 and continue: 2759 / 521

Advancing to step 5:
If we divide 2759 by 521, we get 5 and a remainder of 154.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
If we subtract 2605 from 2759, we get 154.
Bring next digit (4) of the dividend behind the 154 and repeat the process: 1544 / 521

Advancing to step 6:
If we divide 1544 by 521, we get 2 and a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 1552.0
Deduct 1042 from 1544 and we're left with 502.
Fetch the next digit (6) from the dividend, attach it to 502 and continue: 5026 / 521

Step 7:
When dividing 5026 by 521, we get 9 with a remainder of 337.
Write down 9 as next digit of the result. 
Result so far: 15529.0
If we subtract 4689 from 5026, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 8:
The number 521 fits into 3370 6 times, leaving a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 15529.6
Subtract 3126 from 3370 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
When dividing 2440 by 521, we get 4 with a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 15529.64
Deduct 2084 from 2440 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 10:
The number 521 fits into 3560 6 times, leaving a remainder of 434.
Record the quotient 6 as the next digit in the result. 
Result so far: 15529.646
The remainder is 434 after subtracting 3126 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 11:
4340 divided by 521 is 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 15529.6468
Subtracting 4168 from 4340 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 12:
1720 divided by 521 is 3 with a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 15529.64683
If we take 1563 away from 1720, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 13:
521 can be fit into 1570 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 15529.646833
If we take 1563 away from 1570, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 15529.646833, and the remainder is 7e-07.
