We divide 40845809 by 521
Our goal is to divide 40845809 by 521.

Moving on to step 1:
521 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 521

Step 2:
521 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 521

Moving on to step 3:
521 goes into 408 0 times with a remainder of 408.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 408, we get 408.
Grab the next digit (4) from the dividend, add it to 408, then carry on: 4084 / 521

On to step 4:
4084 divided by 521 is 7 with a remainder of 437.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 3647 from 4084 leaves us with 437.
Append the next digit (5) from the dividend to 437 and continue with: 4375 / 521

Step 5:
When dividing 4375 by 521, we get 8 with a remainder of 207.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 207 after subtracting 4168 from 4375.
Fetch the next digit (8) from the dividend, attach it to 207 and continue: 2078 / 521

Step 6:
The number 521 fits into 2078 3 times, leaving a remainder of 515.
Write down 3 as next digit of the result. 
Result so far: 783.0
The remainder is 515 after subtracting 1563 from 2078.
Include the next digit (0) from the dividend after 515, then repeat: 5150 / 521

Going ahead to step 7:
521 can be fit into 5150 9 times, resulting in a remainder of 461.
Write down 9 as next digit of the result. 
Result so far: 7839.0
If we take 4689 away from 5150, we end up with 461.
Fetch the next digit (9) from the dividend, attach it to 461 and continue: 4619 / 521

Going ahead to step 8:
The number 521 fits into 4619 8 times, leaving a remainder of 451.
The number 8 becomes the next digit in our result. 
Result so far: 78398.0
Subtract 4168 from 4619 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Moving on to step 9:
521 can be fit into 4510 8 times, resulting in a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 78398.8
The remainder is 342 after subtracting 4168 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 10:
When dividing 3420 by 521, we get 6 with a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 78398.86
Subtract 3126 from 3420 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 11:
521 can be fit into 2940 5 times, resulting in a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 78398.865
Subtract 2605 from 2940 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 12:
If we divide 3350 by 521, we get 6 and a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 78398.8656
If we take 3126 away from 3350, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 13:
521 goes into 2240 4 times with a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 78398.86564
The remainder is 156 after subtracting 2084 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 14:
When dividing 1560 by 521, we get 2 with a remainder of 518.
The number 2 becomes the next digit in our result. 
Result so far: 78398.865642
Subtracting 1042 from 1560 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 15:
The number 521 fits into 5180 9 times, leaving a remainder of 491.
Write down 9 as next digit of the result. 
Result so far: 78398.8656429
Subtracting 4689 from 5180 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 16:
521 can be fit into 4910 9 times, resulting in a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 78398.86564299
Deduct 4689 from 4910 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The final outcome is 78398.86564299, with a leftover of 2.21e-07.
