We're dividing 52486 by 4 
Our goal is to divide 52486 by 4.

Advancing to step 1:
The number 4 fits into 5 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 4

Moving on to step 2:
The number 4 fits into 12 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 12 away from 12, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 4

Let's proceed to step 3:
When dividing 4 by 4, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 131.0
If we take 4 away from 4, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 4

On to step 4:
The number 4 fits into 8 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 1312.0
Subtract 8 from 8 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 4

Moving on to step 5:
If we divide 6 by 4, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 13121.0
Subtracting 4 from 6 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.

On to step 6:
If we divide 20 by 4, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13121.5
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 7:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13121.5
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.

On to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 13121.5
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.

The final result is 13121.5 with a remainder of 0.0.
