89555802 ÷ 780 
We want to figure out the number of times 89555802 can be divided by 780.

Let's proceed to step 1:
When dividing 8 by 780, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 780

On to step 2:
780 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 780

On to step 3:
780 goes into 895 1 times with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 780 from 895 to get 115.
Take the next digit (5) from the dividend and append it to 115, then repeat: 1155 / 780

Moving on to step 4:
The number 780 fits into 1155 1 times, leaving a remainder of 375.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 375 after subtracting 780 from 1155.
Fetch the next digit (5) from the dividend, attach it to 375 and continue: 3755 / 780

Let's proceed to step 5:
780 goes into 3755 4 times with a remainder of 635.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtract 3120 from 3755 to get 635.
Append the next digit (8) from the dividend to 635 and continue with: 6358 / 780

Moving on to step 6:
When dividing 6358 by 780, we get 8 with a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 1148.0
The remainder is 118 after subtracting 6240 from 6358.
Append the next digit (0) from the dividend to 118 and continue with: 1180 / 780

Step 7:
1180 divided by 780 is 1 with a remainder of 400.
The number 1 becomes the next digit in our result. 
Result so far: 11481.0
Deduct 780 from 1180 and we're left with 400.
Append the next digit (2) from the dividend to 400 and continue with: 4002 / 780

Step 8:
780 can be fit into 4002 5 times, resulting in a remainder of 102.
The number 5 becomes the next digit in our result. 
Result so far: 114815.0
If we subtract 3900 from 4002, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
780 goes into 1020 1 times with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 114815.1
The remainder is 240 after subtracting 780 from 1020.
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 10:
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: 114815.13
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 780 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 114815.13
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.

Step 12:
780 goes into 6000 7 times with a remainder of 540.
Put 7 as the next digit of the answer. 
Result so far: 114815.1307
Subtract 5460 from 6000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 13:
The number 780 fits into 5400 6 times, leaving a remainder of 720.
Put 6 as the next digit of the answer. 
Result so far: 114815.13076
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.

Moving on to step 14:
780 goes into 7200 9 times with a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 114815.130769
Subtracting 7020 from 7200 leaves us 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.

Step 15:
780 goes into 1800 2 times with a remainder of 240.
The next digit of our result is 2. 
Result so far: 114815.1307692
Subtracting 1560 from 1800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
780 can be fit into 2400 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 114815.13076923
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 114815.13076923, and the remainder is 6e-08.
