68604309 ÷ 77 
Our goal is to divide 68604309 by 77.

On to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 77

Advancing to step 2:
77 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 77

On to step 3:
77 can be fit into 686 8 times, resulting in a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 616 away from 686, we end up with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 77

Step 4:
77 goes into 700 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Deduct 693 from 700 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 77

Let's proceed to step 5:
77 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
If we subtract 0 from 74, we get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 77

Step 6:
When dividing 743 by 77, we get 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 8909.0
Subtracting 693 from 743 leaves us with 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 77

Let's proceed to step 7:
The number 77 fits into 500 6 times, leaving a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 89096.0
The remainder is 38 after subtracting 462 from 500.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 77

Advancing to step 8:
When dividing 389 by 77, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 890965.0
Deduct 385 from 389 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 77, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 890965.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
77 goes into 400 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 890965.05
If we subtract 385 from 400, 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.

Going ahead to step 11:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 890965.051
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 12:
730 divided by 77 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 890965.0519
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 13:
When dividing 370 by 77, we get 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 890965.05194
Deduct 308 from 370 and we're left 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.

Let's proceed to step 14:
620 divided by 77 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 890965.051948
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
77 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 890965.051948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
When dividing 400 by 77, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 890965.05194805
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 890965.05194805 with a remaining 1.5e-08.
