We divide 78457809 by 99
We're looking to find how many times 99 goes into 78457809.

Let's proceed to step 1:
7 divided by 99 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 99

Moving on to step 2:
The number 99 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 99

Step 3:
When dividing 784 by 99, we get 7 with a remainder of 91.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 91 after subtracting 693 from 784.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 99

Let's proceed to step 4:
99 goes into 915 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 24 after subtracting 891 from 915.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 99

Going ahead to step 5:
If we divide 247 by 99, we get 2 and a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 792.0
Subtracting 198 from 247 leaves us with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 99

Going ahead to step 6:
If we divide 498 by 99, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 7925.0
Subtract 495 from 498 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 99

Moving on to step 7:
If we divide 30 by 99, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 79250.0
If we subtract 0 from 30, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 99

Let's proceed to step 8:
99 goes into 309 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 792503.0
If we subtract 297 from 309, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
99 can be fit into 120 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 792503.1
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
The number 99 fits into 210 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 792503.12
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 99 fits into 120 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 792503.121
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
If we divide 210 by 99, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 792503.1212
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
120 divided by 99 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 792503.12121
Deduct 99 from 120 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
99 goes into 210 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 792503.121212
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
120 divided by 99 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 792503.1212121
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 16:
If we divide 210 by 99, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 792503.12121212
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 792503.12121212 with a remainder of 1.2e-08.
