Let's divide 63981158 by 647
Let's see how many times 647 fits into 63981158.

On to step 1:
If we divide 6 by 647, we get 0 and 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.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 647

Moving on to step 2:
The number 647 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 647

Step 3:
When dividing 639 by 647, we get 0 with a remainder of 639.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 639 to get 639.
Bring next digit (8) of the dividend behind the 639 and repeat the process: 6398 / 647

Advancing to step 4:
The number 647 fits into 6398 9 times, leaving a remainder of 575.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 5823 from 6398 and we're left with 575.
Bring next digit (1) of the dividend behind the 575 and repeat the process: 5751 / 647

Step 5:
647 can be fit into 5751 8 times, resulting in a remainder of 575.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtracting 5176 from 5751 leaves us with 575.
Include the next digit (1) from the dividend after 575, then repeat: 5751 / 647

Going ahead to step 6:
If we divide 5751 by 647, we get 8 and a remainder of 575.
Write down 8 as next digit of the result. 
Result so far: 988.0
Subtract 5176 from 5751 to get 575.
Append the next digit (5) from the dividend to 575 and continue with: 5755 / 647

Going ahead to step 7:
If we divide 5755 by 647, we get 8 and a remainder of 579.
Put 8 as the next digit of the answer. 
Result so far: 9888.0
Subtract 5176 from 5755 to get 579.
Bring next digit (8) of the dividend behind the 579 and repeat the process: 5798 / 647

Moving on to step 8:
647 can be fit into 5798 8 times, resulting in a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 98888.0
Subtract 5176 from 5798 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

On to step 9:
If we divide 6220 by 647, we get 9 and a remainder of 397.
The number 9 becomes the next digit in our result. 
Result so far: 98888.9
Deduct 5823 from 6220 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 10:
647 can be fit into 3970 6 times, resulting in a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 98888.96
The remainder is 88 after subtracting 3882 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
647 can be fit into 880 1 times, resulting in a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 98888.961
Subtracting 647 from 880 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 12:
When dividing 2330 by 647, we get 3 with a remainder of 389.
Put 3 as the next digit of the answer. 
Result so far: 98888.9613
Subtracting 1941 from 2330 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 13:
647 goes into 3890 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 98888.96136
If we subtract 3882 from 3890, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
80 divided by 647 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 98888.96136
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
647 goes into 800 1 times with a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 98888.9613601
The remainder is 153 after subtracting 647 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 16:
The number 647 fits into 1530 2 times, leaving a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 98888.96136012
The remainder is 236 after subtracting 1294 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

In conclusion, the division gives 98888.96136012 with a balance of 2.36e-07.
