We divide 61991 by 63
We want to figure out the number of times 61991 can be divided by 63.

On to step 1:
6 divided by 63 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 63

Let's proceed to step 2:
63 goes into 61 0 times with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 63

Going ahead to step 3:
63 goes into 619 9 times with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 567 from 619 leaves us with 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 63

Going ahead to step 4:
The number 63 fits into 529 8 times, leaving a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 98.0
The remainder is 25 after subtracting 504 from 529.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 63

Step 5:
63 goes into 251 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 983.0
Deduct 189 from 251 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 6:
When dividing 620 by 63, we get 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 983.9
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
530 divided by 63 is 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 983.98
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 63 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 983.984
If we subtract 252 from 260, 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.

Advancing to step 9:
63 goes into 80 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 983.9841
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
If we divide 170 by 63, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 983.98412
Subtracting 126 from 170 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
440 divided by 63 is 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 983.984126
Subtracting 378 from 440 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
The number 63 fits into 620 9 times, leaving a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 983.9841269
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
The number 63 fits into 530 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 983.98412698
If we subtract 504 from 530, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 983.98412698, and the remainder is 2.6e-08.
