Let's divide 64428747 by 991
Our goal is to divide 64428747 by 991.

Moving on to step 1:
The number 991 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 991

On to step 2:
The number 991 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 991

On to step 3:
If we divide 644 by 991, we get 0 and a remainder of 644.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 644 after subtracting 0 from 644.
Bring next digit (2) of the dividend behind the 644 and repeat the process: 6442 / 991

Going ahead to step 4:
991 can be fit into 6442 6 times, resulting in a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5946 from 6442 leaves us with 496.
Fetch the next digit (8) from the dividend, attach it to 496 and continue: 4968 / 991

On to step 5:
991 goes into 4968 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 65.0
If we take 4955 away from 4968, we end up with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 991

Going ahead to step 6:
137 divided by 991 is 0 with a remainder of 137.
The next digit of our result is 0. 
Result so far: 650.0
The remainder is 137 after subtracting 0 from 137.
Bring next digit (4) of the dividend behind the 137 and repeat the process: 1374 / 991

Let's proceed to step 7:
991 goes into 1374 1 times with a remainder of 383.
The next digit of our result is 1. 
Result so far: 6501.0
The remainder is 383 after subtracting 991 from 1374.
Append the next digit (7) from the dividend to 383 and continue with: 3837 / 991

Let's proceed to step 8:
991 can be fit into 3837 3 times, resulting in a remainder of 864.
The next digit of our result is 3. 
Result so far: 65013.0
Deduct 2973 from 3837 and we're left with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Advancing to step 9:
The number 991 fits into 8640 8 times, leaving a remainder of 712.
The next digit of our result is 8. 
Result so far: 65013.8
Subtracting 7928 from 8640 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 10:
The number 991 fits into 7120 7 times, leaving a remainder of 183.
Record the quotient 7 as the next digit in the result. 
Result so far: 65013.87
The remainder is 183 after subtracting 6937 from 7120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 11:
When dividing 1830 by 991, we get 1 with a remainder of 839.
Use 1 as the next digit of our solution. 
Result so far: 65013.871
Deduct 991 from 1830 and we're left with 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Moving on to step 12:
When dividing 8390 by 991, we get 8 with a remainder of 462.
Use 8 as the next digit of our solution. 
Result so far: 65013.8718
If we take 7928 away from 8390, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 13:
The number 991 fits into 4620 4 times, leaving a remainder of 656.
Record the quotient 4 as the next digit in the result. 
Result so far: 65013.87184
Subtracting 3964 from 4620 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 14:
991 can be fit into 6560 6 times, resulting in a remainder of 614.
Record the quotient 6 as the next digit in the result. 
Result so far: 65013.871846
The remainder is 614 after subtracting 5946 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 15:
When dividing 6140 by 991, we get 6 with a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 65013.8718466
Deduct 5946 from 6140 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The quotient of the division is 65013.8718466, and the remainder is 1.94e-06.
