We look at the division of 97490680 by 31 
We want to figure out the number of times 97490680 can be divided by 31.

Moving on to step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 31

Going ahead to step 2:
The number 31 fits into 97 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 93 from 97 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 31

Going ahead to step 3:
The number 31 fits into 44 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 13 after subtracting 31 from 44.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 31

Moving on to step 4:
139 divided by 31 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 314.0
Subtract 124 from 139 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 31

Let's proceed to step 5:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 3144.0
If we subtract 124 from 150, we get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 31

Advancing to step 6:
If we divide 266 by 31, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 31448.0
The remainder is 18 after subtracting 248 from 266.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 31

Moving on to step 7:
The number 31 fits into 188 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 314486.0
The remainder is 2 after subtracting 186 from 188.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 31

On to step 8:
20 divided by 31 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3144860.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 31, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 3144860.6
Deduct 186 from 200 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 3144860.64
Subtract 124 from 140 to 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.

Advancing to step 11:
When dividing 160 by 31, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3144860.645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
If we divide 50 by 31, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 3144860.6451
Subtracting 31 from 50 leaves us 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 13:
When dividing 190 by 31, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 3144860.64516
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.

Advancing to step 14:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 3144860.645161
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.

Advancing to step 15:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3144860.6451612
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.

Moving on to step 16:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3144860.64516129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 3144860.64516129 with a remainder of 1e-09.
