20993599 divided by 4 
We want to divide 20993599 by 4.

Advancing to step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

On to step 2:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 20 away from 20, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

Going ahead to step 3:
The number 4 fits into 9 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 4

Moving on to step 4:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 524.0
The remainder is 3 after subtracting 16 from 19.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Going ahead to step 5:
33 divided by 4 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 5248.0
Deduct 32 from 33 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

On to step 6:
The number 4 fits into 15 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 52483.0
If we subtract 12 from 15, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

On to step 7:
If we divide 39 by 4, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 524839.0
If we take 36 away from 39, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

Step 8:
The number 4 fits into 39 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 5248399.0
Subtract 36 from 39 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
If we divide 30 by 4, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 5248399.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5248399.75
Subtracting 20 from 20 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5248399.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5248399.75
If we subtract 0 from 0, we 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.

Our division results in 5248399.75 with a remaining 0.0.
