Let's divide 31185478 by 728
We want to figure out the number of times 31185478 can be divided by 728.

Let's proceed to step 1:
The number 728 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 728

Advancing to step 2:
728 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 728

On to step 3:
The number 728 fits into 311 0 times, leaving a remainder of 311.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 311 leaves us with 311.
Grab the next digit (8) from the dividend, add it to 311, then carry on: 3118 / 728

Let's proceed to step 4:
728 can be fit into 3118 4 times, resulting in a remainder of 206.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2912 from 3118 to get 206.
Fetch the next digit (5) from the dividend, attach it to 206 and continue: 2065 / 728

Step 5:
The number 728 fits into 2065 2 times, leaving a remainder of 609.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 1456 from 2065 and we're left with 609.
Take the next digit (4) from the dividend and append it to 609, then repeat: 6094 / 728

Moving on to step 6:
728 goes into 6094 8 times with a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
The remainder is 270 after subtracting 5824 from 6094.
Fetch the next digit (7) from the dividend, attach it to 270 and continue: 2707 / 728

Going ahead to step 7:
If we divide 2707 by 728, we get 3 and a remainder of 523.
The number 3 becomes the next digit in our result. 
Result so far: 4283.0
The remainder is 523 after subtracting 2184 from 2707.
Append the next digit (8) from the dividend to 523 and continue with: 5238 / 728

Step 8:
When dividing 5238 by 728, we get 7 with a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 42837.0
If we take 5096 away from 5238, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 9:
The number 728 fits into 1420 1 times, leaving a remainder of 692.
Use 1 as the next digit of our solution. 
Result so far: 42837.1
Deduct 728 from 1420 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 10:
6920 divided by 728 is 9 with a remainder of 368.
Use 9 as the next digit of our solution. 
Result so far: 42837.19
The remainder is 368 after subtracting 6552 from 6920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 11:
728 goes into 3680 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 42837.195
If we take 3640 away from 3680, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
The number 728 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 42837.195
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
728 goes into 4000 5 times with a remainder of 360.
The number 5 becomes the next digit in our result. 
Result so far: 42837.19505
If we take 3640 away from 4000, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 14:
3600 divided by 728 is 4 with a remainder of 688.
Write down 4 as next digit of the result. 
Result so far: 42837.195054
If we subtract 2912 from 3600, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 15:
The number 728 fits into 6880 9 times, leaving a remainder of 328.
The next digit of our result is 9. 
Result so far: 42837.1950549
Deduct 6552 from 6880 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 16:
If we divide 3280 by 728, we get 4 and a remainder of 368.
The next digit of our result is 4. 
Result so far: 42837.19505494
If we take 2912 away from 3280, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 42837.19505494 with a remainder of 3.68e-07.
