We're dividing 90520718 by 312 
We're looking to find how many times 312 goes into 90520718.

Step 1:
If we divide 9 by 312, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 312

Advancing to step 2:
When dividing 90 by 312, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 312

Advancing to step 3:
If we divide 905 by 312, we get 2 and a remainder of 281.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 281 after subtracting 624 from 905.
Bring next digit (2) of the dividend behind the 281 and repeat the process: 2812 / 312

Going ahead to step 4:
The number 312 fits into 2812 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 2808 from 2812 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 312

Moving on to step 5:
312 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 290.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 312

Going ahead to step 6:
The number 312 fits into 407 1 times, leaving a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 2901.0
The remainder is 95 after subtracting 312 from 407.
Include the next digit (1) from the dividend after 95, then repeat: 951 / 312

Step 7:
The number 312 fits into 951 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 29013.0
If we subtract 936 from 951, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 312

Step 8:
312 can be fit into 158 0 times, resulting in a remainder of 158.
Put 0 as the next digit of the answer. 
Result so far: 290130.0
The remainder is 158 after subtracting 0 from 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
When dividing 1580 by 312, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 290130.5
Deduct 1560 from 1580 and we're left with 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 10:
When dividing 200 by 312, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 290130.5
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
If we divide 2000 by 312, we get 6 and a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 290130.506
Deduct 1872 from 2000 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
When dividing 1280 by 312, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 290130.5064
Deduct 1248 from 1280 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
If we divide 320 by 312, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 290130.50641
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
312 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 290130.50641
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
312 goes into 800 2 times with a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 290130.5064102
If we take 624 away from 800, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
When dividing 1760 by 312, we get 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 290130.50641025
Subtract 1560 from 1760 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 290130.50641025 and a remainder of 2e-07.
