We divide 391653 by 4
We want to figure out the number of times 391653 can be divided by 4.

On to step 1:
If we divide 3 by 4, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

Step 2:
4 goes into 39 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 4

Step 3:
If we divide 31 by 4, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Subtract 28 from 31 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 4

Going ahead to step 4:
The number 4 fits into 36 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 979.0
If we subtract 36 from 36, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 4

Going ahead to step 5:
4 goes into 5 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 9791.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

On to step 6:
13 divided by 4 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 97913.0
If we subtract 12 from 13, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 97913.2
Subtracting 8 from 10 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 4 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 97913.25
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 97913.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 97913.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 97913.25, with a leftover of 0.0.
