We look at the division of 72864542 by 780 
We want to figure out the number of times 72864542 can be divided by 780.

Going ahead to step 1:
7 divided by 780 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 780

Let's proceed to step 2:
When dividing 72 by 780, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 780

Advancing to step 3:
The number 780 fits into 728 0 times, leaving a remainder of 728.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 728, we end up with 728.
Include the next digit (6) from the dividend after 728, then repeat: 7286 / 780

Step 4:
When dividing 7286 by 780, we get 9 with a remainder of 266.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7020 from 7286 and we're left with 266.
Take the next digit (4) from the dividend and append it to 266, then repeat: 2664 / 780

On to step 5:
When dividing 2664 by 780, we get 3 with a remainder of 324.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 2340 from 2664, we get 324.
Grab the next digit (5) from the dividend, add it to 324, then carry on: 3245 / 780

On to step 6:
3245 divided by 780 is 4 with a remainder of 125.
Write down 4 as next digit of the result. 
Result so far: 934.0
The remainder is 125 after subtracting 3120 from 3245.
Append the next digit (4) from the dividend to 125 and continue with: 1254 / 780

Going ahead to step 7:
The number 780 fits into 1254 1 times, leaving a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 9341.0
Subtract 780 from 1254 to get 474.
Append the next digit (2) from the dividend to 474 and continue with: 4742 / 780

Going ahead to step 8:
4742 divided by 780 is 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 93416.0
Subtracting 4680 from 4742 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
The number 780 fits into 620 0 times, leaving a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 93416.0
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
The number 780 fits into 6200 7 times, leaving a remainder of 740.
The number 7 becomes the next digit in our result. 
Result so far: 93416.07
Deduct 5460 from 6200 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 11:
7400 divided by 780 is 9 with a remainder of 380.
Use 9 as the next digit of our solution. 
Result so far: 93416.079
Subtracting 7020 from 7400 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
780 goes into 3800 4 times with a remainder of 680.
Write down 4 as next digit of the result. 
Result so far: 93416.0794
Deduct 3120 from 3800 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 13:
The number 780 fits into 6800 8 times, leaving a remainder of 560.
The next digit of our result is 8. 
Result so far: 93416.07948
If we take 6240 away from 6800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 14:
If we divide 5600 by 780, we get 7 and a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 93416.079487
Subtract 5460 from 5600 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
1400 divided by 780 is 1 with a remainder of 620.
Use 1 as the next digit of our solution. 
Result so far: 93416.0794871
If we subtract 780 from 1400, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 16:
780 can be fit into 6200 7 times, resulting in a remainder of 740.
Write down 7 as next digit of the result. 
Result so far: 93416.07948717
If we subtract 5460 from 6200, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The quotient of the division is 93416.07948717, and the remainder is 7.4e-07.
