We divide 63363867 by 521
We want to divide 63363867 by 521.

Step 1:
The number 521 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 521

Advancing to step 2:
When dividing 63 by 521, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 521

Going ahead to step 3:
521 goes into 633 1 times with a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 521 from 633 to get 112.
Append the next digit (6) from the dividend to 112 and continue with: 1126 / 521

Advancing to step 4:
When dividing 1126 by 521, we get 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1042 from 1126, we get 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 521

Advancing to step 5:
843 divided by 521 is 1 with a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 322 after subtracting 521 from 843.
Bring next digit (8) of the dividend behind the 322 and repeat the process: 3228 / 521

Advancing to step 6:
The number 521 fits into 3228 6 times, leaving a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 1216.0
Deduct 3126 from 3228 and we're left with 102.
Include the next digit (6) from the dividend after 102, then repeat: 1026 / 521

Step 7:
If we divide 1026 by 521, we get 1 and a remainder of 505.
Write down 1 as next digit of the result. 
Result so far: 12161.0
Subtracting 521 from 1026 leaves us with 505.
Fetch the next digit (7) from the dividend, attach it to 505 and continue: 5057 / 521

On to step 8:
If we divide 5057 by 521, we get 9 and a remainder of 368.
The next digit of our result is 9. 
Result so far: 121619.0
If we subtract 4689 from 5057, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
If we divide 3680 by 521, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 121619.7
Subtracting 3647 from 3680 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
When dividing 330 by 521, we get 0 with a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 121619.7
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 11:
If we divide 3300 by 521, we get 6 and a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 121619.706
Subtract 3126 from 3300 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 12:
1740 divided by 521 is 3 with a remainder of 177.
Use 3 as the next digit of our solution. 
Result so far: 121619.7063
Subtract 1563 from 1740 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 13:
The number 521 fits into 1770 3 times, leaving a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 121619.70633
Subtract 1563 from 1770 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Our division results in 121619.70633 with a remaining 0.000207.
