Let's divide 90349744 by 31
Our goal is to divide 90349744 by 31.

Step 1:
9 divided by 31 is 0 with 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.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 31

Step 2:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 90 leaves us with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 31

Let's proceed to step 3:
When dividing 283 by 31, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 279 from 283 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 31

Let's proceed to step 4:
31 can be fit into 44 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtract 31 from 44 to get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 31

Let's proceed to step 5:
31 goes into 139 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 2914.0
If we subtract 124 from 139, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 31

Let's proceed to step 6:
31 goes into 157 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 29145.0
Deduct 155 from 157 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 31

Moving on to step 7:
31 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 291450.0
The remainder is 24 after subtracting 0 from 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 31

Step 8:
When dividing 244 by 31, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 2914507.0
Subtract 217 from 244 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2914507.8
Subtract 248 from 270 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
220 divided by 31 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2914507.87
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.

On to step 11:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2914507.87
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
31 goes into 300 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 2914507.8709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
31 goes into 210 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2914507.87096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
If we divide 240 by 31, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 2914507.870967
Deduct 217 from 240 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
When dividing 230 by 31, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2914507.8709677
Deduct 217 from 230 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 2914507.8709677 with a remaining 1.3e-07.
