We're dividing 4986 by 79 
Our goal is to divide 4986 by 79.

Step 1:
4 divided by 79 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 79

On to step 2:
The number 79 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 79

Let's proceed to step 3:
If we divide 498 by 79, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 474 from 498 leaves us with 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 79

Advancing to step 4:
The number 79 fits into 246 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 9 after subtracting 237 from 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 5:
79 goes into 90 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 63.1
Subtracting 79 from 90 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 6:
When dividing 110 by 79, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 63.11
Deduct 79 from 110 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 63.11 with a remaining 0.031.
