939943 divided by 4 
We're looking to find how many times 4 goes into 939943.

On to step 1:
If we divide 9 by 4, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 1 after subtracting 8 from 9.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 4

Moving on to step 2:
When dividing 13 by 4, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 12 from 13 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Going ahead to step 3:
4 can be fit into 19 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtracting 16 from 19 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

Going ahead to step 4:
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: 2349.0
Deduct 36 from 39 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Step 5:
If we divide 34 by 4, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 23498.0
Subtract 32 from 34 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

On to step 6:
When dividing 23 by 4, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 234985.0
Subtracting 20 from 23 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 234985.7
If we take 28 away from 30, we end up 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.

Step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 234985.75
Deduct 20 from 20 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 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 234985.75
Subtracting 0 from 0 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.

Going ahead to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 234985.75
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 quotient of the division is 234985.75, and the remainder is 0.0.
