78964203 divided by 780 
We want to figure out the number of times 78964203 can be divided by 780.

Let's proceed to step 1:
780 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 780

On to step 2:
When dividing 78 by 780, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 780

On to step 3:
780 goes into 789 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 780 from 789 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 780

Advancing to step 4:
780 goes into 96 0 times with a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 96 leaves us with 96.
Take the next digit (4) from the dividend and append it to 96, then repeat: 964 / 780

Going ahead to step 5:
964 divided by 780 is 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 101.0
If we subtract 780 from 964, we get 184.
Fetch the next digit (2) from the dividend, attach it to 184 and continue: 1842 / 780

Moving on to step 6:
When dividing 1842 by 780, we get 2 with a remainder of 282.
Use 2 as the next digit of our solution. 
Result so far: 1012.0
Subtracting 1560 from 1842 leaves us with 282.
Take the next digit (0) from the dividend and append it to 282, then repeat: 2820 / 780

On to step 7:
The number 780 fits into 2820 3 times, leaving a remainder of 480.
The next digit of our result is 3. 
Result so far: 10123.0
If we subtract 2340 from 2820, we get 480.
Fetch the next digit (3) from the dividend, attach it to 480 and continue: 4803 / 780

Let's proceed to step 8:
The number 780 fits into 4803 6 times, leaving a remainder of 123.
The next digit of our result is 6. 
Result so far: 101236.0
Deduct 4680 from 4803 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
780 can be fit into 1230 1 times, resulting in a remainder of 450.
Put 1 as the next digit of the answer. 
Result so far: 101236.1
If we subtract 780 from 1230, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
When dividing 4500 by 780, we get 5 with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 101236.15
Subtracting 3900 from 4500 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 11:
The number 780 fits into 6000 7 times, leaving a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 101236.157
The remainder is 540 after subtracting 5460 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 12:
780 can be fit into 5400 6 times, resulting in a remainder of 720.
Record the quotient 6 as the next digit in the result. 
Result so far: 101236.1576
Subtracting 4680 from 5400 leaves us 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.

Let's proceed to step 13:
If we divide 7200 by 780, we get 9 and a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 101236.15769
If we take 7020 away from 7200, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
780 goes into 1800 2 times with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 101236.157692
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
780 goes into 2400 3 times with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 101236.1576923
The remainder is 60 after subtracting 2340 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
When dividing 600 by 780, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 101236.1576923
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 101236.1576923, with a leftover of 6e-07.
