Let's divide 4427423 by 991
We want to divide 4427423 by 991.

On to step 1:
991 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 991

Moving on to step 2:
If we divide 44 by 991, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 991

Going ahead to step 3:
If we divide 442 by 991, we get 0 and a remainder of 442.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 442, we end up with 442.
Grab the next digit (7) from the dividend, add it to 442, then carry on: 4427 / 991

Advancing to step 4:
991 goes into 4427 4 times with a remainder of 463.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3964 from 4427 leaves us with 463.
Append the next digit (4) from the dividend to 463 and continue with: 4634 / 991

Moving on to step 5:
If we divide 4634 by 991, we get 4 and a remainder of 670.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 3964 from 4634 and we're left with 670.
Fetch the next digit (2) from the dividend, attach it to 670 and continue: 6702 / 991

Going ahead to step 6:
991 can be fit into 6702 6 times, resulting in a remainder of 756.
The number 6 becomes the next digit in our result. 
Result so far: 446.0
If we take 5946 away from 6702, we end up with 756.
Append the next digit (3) from the dividend to 756 and continue with: 7563 / 991

On to step 7:
7563 divided by 991 is 7 with a remainder of 626.
The number 7 becomes the next digit in our result. 
Result so far: 4467.0
If we subtract 6937 from 7563, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 8:
The number 991 fits into 6260 6 times, leaving a remainder of 314.
Use 6 as the next digit of our solution. 
Result so far: 4467.6
If we take 5946 away from 6260, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 9:
The number 991 fits into 3140 3 times, leaving a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 4467.63
If we take 2973 away from 3140, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 10:
991 can be fit into 1670 1 times, resulting in a remainder of 679.
The number 1 becomes the next digit in our result. 
Result so far: 4467.631
If we take 991 away from 1670, we end up with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Moving on to step 11:
6790 divided by 991 is 6 with a remainder of 844.
The number 6 becomes the next digit in our result. 
Result so far: 4467.6316
If we take 5946 away from 6790, we end up with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Let's proceed to step 12:
991 goes into 8440 8 times with a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 4467.63168
The remainder is 512 after subtracting 7928 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 13:
991 goes into 5120 5 times with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 4467.631685
If we subtract 4955 from 5120, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 14:
991 can be fit into 1650 1 times, resulting in a remainder of 659.
Use 1 as the next digit of our solution. 
Result so far: 4467.6316851
If we subtract 991 from 1650, we get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Let's proceed to step 15:
991 goes into 6590 6 times with a remainder of 644.
Write down 6 as next digit of the result. 
Result so far: 4467.63168516
If we take 5946 away from 6590, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Our division results in 4467.63168516 with a remaining 6.44e-07.
