We're dividing 72454491 by 780 
Our goal is to divide 72454491 by 780.

Advancing to step 1:
The number 780 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 780

Advancing to step 2:
72 divided by 780 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 780

Going ahead to step 3:
780 goes into 724 0 times with a remainder of 724.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 724 leaves us with 724.
Grab the next digit (5) from the dividend, add it to 724, then carry on: 7245 / 780

On to step 4:
When dividing 7245 by 780, we get 9 with a remainder of 225.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 225 after subtracting 7020 from 7245.
Grab the next digit (4) from the dividend, add it to 225, then carry on: 2254 / 780

Step 5:
If we divide 2254 by 780, we get 2 and a remainder of 694.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we subtract 1560 from 2254, we get 694.
Bring next digit (4) of the dividend behind the 694 and repeat the process: 6944 / 780

On to step 6:
When dividing 6944 by 780, we get 8 with a remainder of 704.
Use 8 as the next digit of our solution. 
Result so far: 928.0
If we take 6240 away from 6944, we end up with 704.
Take the next digit (9) from the dividend and append it to 704, then repeat: 7049 / 780

Advancing to step 7:
780 goes into 7049 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 9289.0
If we take 7020 away from 7049, we end up with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 780

Moving on to step 8:
When dividing 291 by 780, we get 0 with a remainder of 291.
The next digit of our result is 0. 
Result so far: 92890.0
If we subtract 0 from 291, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 9:
780 can be fit into 2910 3 times, resulting in a remainder of 570.
Write down 3 as next digit of the result. 
Result so far: 92890.3
Subtract 2340 from 2910 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 10:
If we divide 5700 by 780, we get 7 and a remainder of 240.
Write down 7 as next digit of the result. 
Result so far: 92890.37
The remainder is 240 after subtracting 5460 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
If we divide 2400 by 780, we get 3 and a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 92890.373
Subtract 2340 from 2400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 780, we get 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 92890.373
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 13:
780 goes into 6000 7 times with a remainder of 540.
The next digit of our result is 7. 
Result so far: 92890.37307
If we take 5460 away from 6000, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 14:
When dividing 5400 by 780, we get 6 with a remainder of 720.
Use 6 as the next digit of our solution. 
Result so far: 92890.373076
If we take 4680 away from 5400, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 15:
780 goes into 7200 9 times with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 92890.3730769
Subtract 7020 from 7200 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
1800 divided by 780 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 92890.37307692
Subtract 1560 from 1800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 92890.37307692 and a remainder of 2.4e-07.
