We divide 18135490 by 780
We want to figure out the number of times 18135490 can be divided by 780.

On to step 1:
780 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 780

Advancing to step 2:
The number 780 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 780

Advancing to step 3:
780 goes into 181 0 times with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Take the next digit (3) from the dividend and append it to 181, then repeat: 1813 / 780

Step 4:
1813 divided by 780 is 2 with a remainder of 253.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1560 from 1813 and we're left with 253.
Grab the next digit (5) from the dividend, add it to 253, then carry on: 2535 / 780

Advancing to step 5:
780 goes into 2535 3 times with a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 2340 from 2535 to get 195.
Take the next digit (4) from the dividend and append it to 195, then repeat: 1954 / 780

On to step 6:
780 can be fit into 1954 2 times, resulting in a remainder of 394.
The next digit of our result is 2. 
Result so far: 232.0
Subtracting 1560 from 1954 leaves us with 394.
Include the next digit (9) from the dividend after 394, then repeat: 3949 / 780

Advancing to step 7:
780 goes into 3949 5 times with a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 2325.0
The remainder is 49 after subtracting 3900 from 3949.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 780

Going ahead to step 8:
The number 780 fits into 490 0 times, leaving a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 23250.0
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 9:
4900 divided by 780 is 6 with a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 23250.6
Subtract 4680 from 4900 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
2200 divided by 780 is 2 with a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 23250.62
If we take 1560 away from 2200, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 11:
If we divide 6400 by 780, we get 8 and a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 23250.628
If we subtract 6240 from 6400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
When dividing 1600 by 780, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 23250.6282
If we take 1560 away from 1600, 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 13:
400 divided by 780 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 23250.6282
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
The number 780 fits into 4000 5 times, leaving a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 23250.628205
The remainder is 100 after subtracting 3900 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
780 goes into 1000 1 times with a remainder of 220.
The next digit of our result is 1. 
Result so far: 23250.6282051
The remainder is 220 after subtracting 780 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
780 goes into 2200 2 times with a remainder of 640.
Record the quotient 2 as the next digit in the result. 
Result so far: 23250.62820512
Subtract 1560 from 2200 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 23250.62820512, with a leftover of 6.4e-07.
