We look at the division of 39479783 by 915 
We want to divide 39479783 by 915.

Step 1:
915 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 915

On to step 2:
39 divided by 915 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 915

Step 3:
When dividing 394 by 915, we get 0 with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 394 leaves us with 394.
Grab the next digit (7) from the dividend, add it to 394, then carry on: 3947 / 915

Let's proceed to step 4:
915 goes into 3947 4 times with a remainder of 287.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3660 from 3947, we get 287.
Include the next digit (9) from the dividend after 287, then repeat: 2879 / 915

Step 5:
The number 915 fits into 2879 3 times, leaving a remainder of 134.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 2745 from 2879 and we're left with 134.
Fetch the next digit (7) from the dividend, attach it to 134 and continue: 1347 / 915

Moving on to step 6:
When dividing 1347 by 915, we get 1 with a remainder of 432.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
Subtract 915 from 1347 to get 432.
Bring next digit (8) of the dividend behind the 432 and repeat the process: 4328 / 915

Step 7:
915 goes into 4328 4 times with a remainder of 668.
Record the quotient 4 as the next digit in the result. 
Result so far: 4314.0
Subtracting 3660 from 4328 leaves us with 668.
Append the next digit (3) from the dividend to 668 and continue with: 6683 / 915

Let's proceed to step 8:
When dividing 6683 by 915, we get 7 with a remainder of 278.
The next digit of our result is 7. 
Result so far: 43147.0
The remainder is 278 after subtracting 6405 from 6683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 9:
915 goes into 2780 3 times with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 43147.3
If we subtract 2745 from 2780, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
915 can be fit into 350 0 times, resulting in a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 43147.3
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
915 can be fit into 3500 3 times, resulting in a remainder of 755.
The next digit of our result is 3. 
Result so far: 43147.303
Deduct 2745 from 3500 and we're left with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Step 12:
When dividing 7550 by 915, we get 8 with a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 43147.3038
If we subtract 7320 from 7550, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 13:
915 can be fit into 2300 2 times, resulting in a remainder of 470.
The next digit of our result is 2. 
Result so far: 43147.30382
If we subtract 1830 from 2300, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 14:
4700 divided by 915 is 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 43147.303825
If we subtract 4575 from 4700, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 15:
If we divide 1250 by 915, we get 1 and a remainder of 335.
Write down 1 as next digit of the result. 
Result so far: 43147.3038251
Subtracting 915 from 1250 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 16:
If we divide 3350 by 915, we get 3 and a remainder of 605.
Record the quotient 3 as the next digit in the result. 
Result so far: 43147.30382513
Deduct 2745 from 3350 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

The quotient of the division is 43147.30382513, and the remainder is 6.05e-07.
