We're dividing 31890320 by 915 
We want to divide 31890320 by 915.

Step 1:
The number 915 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 915

Let's proceed to step 2:
The number 915 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 915

Step 3:
When dividing 318 by 915, we get 0 with a remainder of 318.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 318, we get 318.
Take the next digit (9) from the dividend and append it to 318, then repeat: 3189 / 915

Going ahead to step 4:
The number 915 fits into 3189 3 times, leaving a remainder of 444.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2745 from 3189 leaves us with 444.
Fetch the next digit (0) from the dividend, attach it to 444 and continue: 4440 / 915

On to step 5:
915 goes into 4440 4 times with a remainder of 780.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 3660 from 4440, we get 780.
Take the next digit (3) from the dividend and append it to 780, then repeat: 7803 / 915

Moving on to step 6:
When dividing 7803 by 915, we get 8 with a remainder of 483.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
Subtract 7320 from 7803 to get 483.
Take the next digit (2) from the dividend and append it to 483, then repeat: 4832 / 915

Advancing to step 7:
915 goes into 4832 5 times with a remainder of 257.
The next digit of our result is 5. 
Result so far: 3485.0
If we subtract 4575 from 4832, we get 257.
Append the next digit (0) from the dividend to 257 and continue with: 2570 / 915

Moving on to step 8:
When dividing 2570 by 915, we get 2 with a remainder of 740.
The next digit of our result is 2. 
Result so far: 34852.0
Deduct 1830 from 2570 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 9:
The number 915 fits into 7400 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 34852.8
Subtracting 7320 from 7400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 915 is 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 34852.8
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 11:
915 goes into 8000 8 times with a remainder of 680.
Write down 8 as next digit of the result. 
Result so far: 34852.808
Subtracting 7320 from 8000 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 12:
6800 divided by 915 is 7 with a remainder of 395.
Record the quotient 7 as the next digit in the result. 
Result so far: 34852.8087
If we take 6405 away from 6800, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 13:
3950 divided by 915 is 4 with a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 34852.80874
If we subtract 3660 from 3950, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
915 can be fit into 2900 3 times, resulting in a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 34852.808743
If we take 2745 away from 2900, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 15:
1550 divided by 915 is 1 with a remainder of 635.
Record the quotient 1 as the next digit in the result. 
Result so far: 34852.8087431
If we take 915 away from 1550, we end up with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 16:
The number 915 fits into 6350 6 times, leaving a remainder of 860.
Record the quotient 6 as the next digit in the result. 
Result so far: 34852.80874316
Subtracting 5490 from 6350 leaves us with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

In conclusion, the division gives 34852.80874316 with a balance of 8.6e-07.
