We look at the division of 6885439 by 77 
We want to divide 6885439 by 77.

Step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 77

Let's proceed to step 2:
When dividing 68 by 77, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 77

On to step 3:
77 can be fit into 688 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 616 from 688 to get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 77

Step 4:
725 divided by 77 is 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 89.0
The remainder is 32 after subtracting 693 from 725.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 77

On to step 5:
If we divide 324 by 77, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 894.0
If we subtract 308 from 324, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 77

Going ahead to step 6:
If we divide 163 by 77, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 8942.0
Subtract 154 from 163 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 77

Let's proceed to step 7:
The number 77 fits into 99 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 89421.0
If we subtract 77 from 99, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
When dividing 220 by 77, we get 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 89421.2
Subtracting 154 from 220 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
When dividing 660 by 77, we get 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 89421.28
If we take 616 away from 660, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
77 can be fit into 440 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 89421.285
If we take 385 away from 440, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
77 goes into 550 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 89421.2857
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
The number 77 fits into 110 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 89421.28571
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
77 can be fit into 330 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 89421.285714
If we take 308 away from 330, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
If we divide 220 by 77, we get 2 and a remainder of 66.
The next digit of our result is 2. 
Result so far: 89421.2857142
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 15:
77 can be fit into 660 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 89421.28571428
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 89421.28571428 with a remaining 4.4e-08.
