77812788 ÷ 69 
We want to figure out the number of times 77812788 can be divided by 69.

Step 1:
The number 69 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 69

Let's proceed to step 2:
The number 69 fits into 77 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 69 from 77 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 69

Step 3:
88 divided by 69 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 69 from 88, we get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 69

Let's proceed to step 4:
191 divided by 69 is 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we take 138 away from 191, we end up with 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 69

Let's proceed to step 5:
When dividing 532 by 69, we get 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 1127.0
Subtract 483 from 532 to get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 69

On to step 6:
69 can be fit into 497 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 11277.0
Subtract 483 from 497 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 69

Moving on to step 7:
The number 69 fits into 148 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 112772.0
Deduct 138 from 148 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 69

Moving on to step 8:
69 goes into 108 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1127721.0
The remainder is 39 after subtracting 69 from 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
69 goes into 390 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1127721.5
Subtracting 345 from 390 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
If we divide 450 by 69, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 1127721.56
Subtracting 414 from 450 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 69 fits into 360 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1127721.565
If we subtract 345 from 360, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
The number 69 fits into 150 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 1127721.5652
Deduct 138 from 150 and we're left 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.

Going ahead to step 13:
When dividing 120 by 69, we get 1 with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1127721.56521
If we take 69 away from 120, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 14:
When dividing 510 by 69, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 1127721.565217
The remainder is 27 after subtracting 483 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 15:
69 can be fit into 270 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 1127721.5652173
Subtracting 207 from 270 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 16:
69 goes into 630 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 1127721.56521739
Deduct 621 from 630 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 1127721.56521739 with a remaining 9e-09.
