Let's divide 30643990 by 918
Let's see how many times 918 fits into 30643990.

Going ahead to step 1:
918 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 918

Step 2:
The number 918 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 918

Let's proceed to step 3:
918 goes into 306 0 times with a remainder of 306.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Grab the next digit (4) from the dividend, add it to 306, then carry on: 3064 / 918

Going ahead to step 4:
The number 918 fits into 3064 3 times, leaving a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2754 from 3064 and we're left with 310.
Bring next digit (3) of the dividend behind the 310 and repeat the process: 3103 / 918

Advancing to step 5:
If we divide 3103 by 918, we get 3 and a remainder of 349.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 2754 from 3103 to get 349.
Include the next digit (9) from the dividend after 349, then repeat: 3499 / 918

Moving on to step 6:
918 can be fit into 3499 3 times, resulting in a remainder of 745.
The number 3 becomes the next digit in our result. 
Result so far: 333.0
The remainder is 745 after subtracting 2754 from 3499.
Bring next digit (9) of the dividend behind the 745 and repeat the process: 7459 / 918

Step 7:
The number 918 fits into 7459 8 times, leaving a remainder of 115.
Put 8 as the next digit of the answer. 
Result so far: 3338.0
The remainder is 115 after subtracting 7344 from 7459.
Include the next digit (0) from the dividend after 115, then repeat: 1150 / 918

Step 8:
918 can be fit into 1150 1 times, resulting in a remainder of 232.
Put 1 as the next digit of the answer. 
Result so far: 33381.0
The remainder is 232 after subtracting 918 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 9:
918 can be fit into 2320 2 times, resulting in a remainder of 484.
The next digit of our result is 2. 
Result so far: 33381.2
Subtract 1836 from 2320 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 10:
918 goes into 4840 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 33381.25
Deduct 4590 from 4840 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
The number 918 fits into 2500 2 times, leaving a remainder of 664.
Record the quotient 2 as the next digit in the result. 
Result so far: 33381.252
If we take 1836 away from 2500, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 12:
The number 918 fits into 6640 7 times, leaving a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 33381.2527
If we subtract 6426 from 6640, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 13:
The number 918 fits into 2140 2 times, leaving a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 33381.25272
If we subtract 1836 from 2140, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 14:
When dividing 3040 by 918, we get 3 with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 33381.252723
Deduct 2754 from 3040 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 15:
2860 divided by 918 is 3 with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 33381.2527233
Subtracting 2754 from 2860 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final result is 33381.2527233 with a remainder of 1.06e-06.
