We're dividing 98175789 by 521 
We want to divide 98175789 by 521.

Going ahead to step 1:
9 divided by 521 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 521

Advancing to step 2:
The number 521 fits into 98 0 times, leaving a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Grab the next digit (1) from the dividend, add it to 98, then carry on: 981 / 521

On to step 3:
521 can be fit into 981 1 times, resulting in a remainder of 460.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 521 from 981 and we're left with 460.
Fetch the next digit (7) from the dividend, attach it to 460 and continue: 4607 / 521

Advancing to step 4:
4607 divided by 521 is 8 with a remainder of 439.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 4168 from 4607 leaves us with 439.
Bring next digit (5) of the dividend behind the 439 and repeat the process: 4395 / 521

Advancing to step 5:
When dividing 4395 by 521, we get 8 with a remainder of 227.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Subtracting 4168 from 4395 leaves us with 227.
Bring next digit (7) of the dividend behind the 227 and repeat the process: 2277 / 521

Let's proceed to step 6:
2277 divided by 521 is 4 with a remainder of 193.
Put 4 as the next digit of the answer. 
Result so far: 1884.0
Deduct 2084 from 2277 and we're left with 193.
Grab the next digit (8) from the dividend, add it to 193, then carry on: 1938 / 521

On to step 7:
521 goes into 1938 3 times with a remainder of 375.
Record the quotient 3 as the next digit in the result. 
Result so far: 18843.0
If we subtract 1563 from 1938, we get 375.
Grab the next digit (9) from the dividend, add it to 375, then carry on: 3759 / 521

Moving on to step 8:
521 can be fit into 3759 7 times, resulting in a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 188437.0
If we take 3647 away from 3759, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
When dividing 1120 by 521, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 188437.2
Subtract 1042 from 1120 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 10:
When dividing 780 by 521, we get 1 with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 188437.21
If we take 521 away from 780, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 11:
521 goes into 2590 4 times with a remainder of 506.
The next digit of our result is 4. 
Result so far: 188437.214
Subtracting 2084 from 2590 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 12:
The number 521 fits into 5060 9 times, leaving a remainder of 371.
The next digit of our result is 9. 
Result so far: 188437.2149
If we take 4689 away from 5060, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 13:
521 can be fit into 3710 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 188437.21497
The remainder is 63 after subtracting 3647 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 14:
630 divided by 521 is 1 with a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 188437.214971
Subtracting 521 from 630 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 15:
The number 521 fits into 1090 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 188437.2149712
Deduct 1042 from 1090 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
When dividing 480 by 521, we get 0 with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 188437.2149712
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 188437.2149712 with a remainder of 4.8e-07.
