Let's divide 17485863 by 4
We want to divide 17485863 by 4.

On to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 4

Advancing to step 2:
When dividing 17 by 4, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 16 away from 17, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Moving on to step 3:
14 divided by 4 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 12 from 14 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

Advancing to step 4:
4 goes into 28 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 437.0
Subtract 28 from 28 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 4

Let's proceed to step 5:
5 divided by 4 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4371.0
Subtracting 4 from 5 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Advancing to step 6:
If we divide 18 by 4, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 43714.0
If we take 16 away from 18, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Let's proceed to step 7:
4 goes into 26 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 437146.0
The remainder is 2 after subtracting 24 from 26.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

Going ahead to step 8:
When dividing 23 by 4, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 4371465.0
Subtract 20 from 23 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.

Let's proceed to step 9:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 4371465.7
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.

Going ahead to step 10:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4371465.75
If we take 20 away from 20, we end up 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.

On to step 11:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4371465.75
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: 4371465.75
If we take 0 away from 0, we end up 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.

Our division results in 4371465.75 with a remaining 0.0.
