We divide 90475724 by 31
We want to divide 90475724 by 31.

Going ahead to step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 31

Moving on to step 2:
90 divided by 31 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 28 after subtracting 62 from 90.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 31

On to step 3:
When dividing 284 by 31, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 279 from 284 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 31

Moving on to step 4:
If we divide 57 by 31, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 291.0
Deduct 31 from 57 and we're left with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 31

Step 5:
When dividing 265 by 31, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 2918.0
Subtract 248 from 265 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 31

On to step 6:
When dividing 177 by 31, we get 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 29185.0
The remainder is 22 after subtracting 155 from 177.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 31

Advancing to step 7:
31 goes into 222 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 291857.0
If we subtract 217 from 222, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 31

On to step 8:
54 divided by 31 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 2918571.0
The remainder is 23 after subtracting 31 from 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2918571.7
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
31 goes into 130 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 2918571.74
The remainder is 6 after subtracting 124 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
31 goes into 60 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 2918571.741
Deduct 31 from 60 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
290 divided by 31 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2918571.7419
Deduct 279 from 290 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
31 can be fit into 110 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2918571.74193
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
170 divided by 31 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2918571.741935
Subtract 155 from 170 to get 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 15:
When dividing 150 by 31, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 2918571.7419354
Subtracting 124 from 150 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 16:
When dividing 260 by 31, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2918571.74193548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 2918571.74193548 with a remainder of 1.2e-08.
