We're dividing 52530840 by 521 
We want to figure out the number of times 52530840 can be divided by 521.

Advancing to step 1:
When dividing 5 by 521, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 521

Let's proceed to step 2:
52 divided by 521 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 521

Moving on to step 3:
When dividing 525 by 521, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 521 from 525 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 521

Let's proceed to step 4:
521 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 43, we get 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 521

Moving on to step 5:
521 goes into 430 0 times with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 430 to get 430.
Append the next digit (8) from the dividend to 430 and continue with: 4308 / 521

Advancing to step 6:
521 can be fit into 4308 8 times, resulting in a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
Deduct 4168 from 4308 and we're left with 140.
Include the next digit (4) from the dividend after 140, then repeat: 1404 / 521

Going ahead to step 7:
The number 521 fits into 1404 2 times, leaving a remainder of 362.
Use 2 as the next digit of our solution. 
Result so far: 10082.0
The remainder is 362 after subtracting 1042 from 1404.
Include the next digit (0) from the dividend after 362, then repeat: 3620 / 521

On to step 8:
The number 521 fits into 3620 6 times, leaving a remainder of 494.
The number 6 becomes the next digit in our result. 
Result so far: 100826.0
If we take 3126 away from 3620, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 9:
521 can be fit into 4940 9 times, resulting in a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 100826.9
Deduct 4689 from 4940 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 10:
521 goes into 2510 4 times with a remainder of 426.
Record the quotient 4 as the next digit in the result. 
Result so far: 100826.94
Subtracting 2084 from 2510 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 11:
521 goes into 4260 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 100826.948
If we take 4168 away from 4260, we end up 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 12:
If we divide 920 by 521, we get 1 and a remainder of 399.
The next digit of our result is 1. 
Result so far: 100826.9481
The remainder is 399 after subtracting 521 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 13:
3990 divided by 521 is 7 with a remainder of 343.
The next digit of our result is 7. 
Result so far: 100826.94817
Subtracting 3647 from 3990 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 14:
The number 521 fits into 3430 6 times, leaving a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 100826.948176
Subtracting 3126 from 3430 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 15:
The number 521 fits into 3040 5 times, leaving a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 100826.9481765
Subtracting 2605 from 3040 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 16:
The number 521 fits into 4350 8 times, leaving a remainder of 182.
The number 8 becomes the next digit in our result. 
Result so far: 100826.94817658
The remainder is 182 after subtracting 4168 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

In conclusion, the division gives 100826.94817658 with a balance of 1.82e-07.
