30573236 divided by 874 
We want to figure out the number of times 30573236 can be divided by 874.

On to step 1:
3 divided by 874 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 874

On to step 2:
874 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 874

Moving on to step 3:
874 goes into 305 0 times with a remainder of 305.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 305 after subtracting 0 from 305.
Fetch the next digit (7) from the dividend, attach it to 305 and continue: 3057 / 874

Step 4:
874 goes into 3057 3 times with a remainder of 435.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 2622 away from 3057, we end up with 435.
Bring next digit (3) of the dividend behind the 435 and repeat the process: 4353 / 874

Going ahead to step 5:
The number 874 fits into 4353 4 times, leaving a remainder of 857.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 3496 from 4353 and we're left with 857.
Include the next digit (2) from the dividend after 857, then repeat: 8572 / 874

On to step 6:
874 goes into 8572 9 times with a remainder of 706.
Write down 9 as next digit of the result. 
Result so far: 349.0
The remainder is 706 after subtracting 7866 from 8572.
Fetch the next digit (3) from the dividend, attach it to 706 and continue: 7063 / 874

Going ahead to step 7:
874 can be fit into 7063 8 times, resulting in a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 3498.0
Subtract 6992 from 7063 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 874

Advancing to step 8:
When dividing 716 by 874, we get 0 with a remainder of 716.
The number 0 becomes the next digit in our result. 
Result so far: 34980.0
If we take 0 away from 716, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Step 9:
When dividing 7160 by 874, we get 8 with a remainder of 168.
The next digit of our result is 8. 
Result so far: 34980.8
If we subtract 6992 from 7160, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
When dividing 1680 by 874, we get 1 with a remainder of 806.
Put 1 as the next digit of the answer. 
Result so far: 34980.81
Subtracting 874 from 1680 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Moving on to step 11:
If we divide 8060 by 874, we get 9 and a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 34980.819
Subtract 7866 from 8060 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 12:
1940 divided by 874 is 2 with a remainder of 192.
The next digit of our result is 2. 
Result so far: 34980.8192
If we subtract 1748 from 1940, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
874 goes into 1920 2 times with a remainder of 172.
The next digit of our result is 2. 
Result so far: 34980.81922
Subtracting 1748 from 1920 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final result is 34980.81922 with a remainder of 0.000172.
