We look at the division of 486798 by 31 
Let's see how many times 31 fits into 486798.

Step 1:
31 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 31

Moving on to step 2:
If we divide 48 by 31, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 31 from 48 to get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 31

Let's proceed to step 3:
176 divided by 31 is 5 with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 21 after subtracting 155 from 176.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 31

On to step 4:
217 divided by 31 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtracting 217 from 217 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 31

On to step 5:
31 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 1570.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 31

Let's proceed to step 6:
98 divided by 31 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 15703.0
If we take 93 away from 98, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 31, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 15703.1
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
When dividing 190 by 31, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15703.16
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 15703.161
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
When dividing 90 by 31, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 15703.1612
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 15703.16129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
10 divided by 31 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15703.16129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 15703.1612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 31, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15703.16129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 15703.16129032, with a leftover of 8e-09.
