We look at the division of 98645428 by 31 
We want to divide 98645428 by 31.

Going ahead to step 1:
If we divide 9 by 31, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 31

Step 2:
If we divide 98 by 31, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 5 after subtracting 93 from 98.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 31

Going ahead to step 3:
31 goes into 56 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 31 from 56 to get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 31

Going ahead to step 4:
When dividing 254 by 31, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
Deduct 248 from 254 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 31

Advancing to step 5:
31 goes into 65 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 3182.0
If we take 62 away from 65, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 31

Advancing to step 6:
34 divided by 31 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 31821.0
Subtract 31 from 34 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 31

Let's proceed to step 7:
If we divide 32 by 31, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 318211.0
Subtracting 31 from 32 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 31

On to step 8:
31 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 3182110.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
The number 31 fits into 180 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3182110.5
The remainder is 25 after subtracting 155 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
When dividing 250 by 31, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3182110.58
If we subtract 248 from 250, we 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.

On to step 11:
The number 31 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3182110.58
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
If we divide 200 by 31, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 3182110.5806
Subtract 186 from 200 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3182110.58064
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
31 can be fit into 160 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 3182110.580645
Subtracting 155 from 160 leaves us 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.

Let's proceed to step 15:
50 divided by 31 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 3182110.5806451
If we take 31 away from 50, we end up 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.

Going ahead to step 16:
31 goes into 190 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3182110.58064516
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 3182110.58064516 with a remainder of 4e-09.
