98405 ÷ 31 
We want to divide 98405 by 31.

Moving on to step 1:
If we divide 9 by 31, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 31

Moving on to step 2:
98 divided by 31 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 5 after subtracting 93 from 98.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 31

Moving on to step 3:
31 can be fit into 54 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 31 away from 54, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 31

On to step 4:
When dividing 230 by 31, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 317.0
If we take 217 away from 230, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 31

Going ahead to step 5:
The number 31 fits into 135 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 3174.0
Subtract 124 from 135 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 6:
If we divide 110 by 31, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3174.3
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
When dividing 170 by 31, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3174.35
Deduct 155 from 170 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
31 goes into 150 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 3174.354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
31 goes into 260 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 3174.3548
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 3174.35483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 3174.354838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
31 goes into 220 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3174.3548387
Subtracting 217 from 220 leaves us with 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 13:
30 divided by 31 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3174.3548387
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 3174.3548387 with a remainder of 3e-08.
