661878 divided by 77 
Our goal is to divide 661878 by 77.

Advancing to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 77

Moving on to step 2:
When dividing 66 by 77, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 77

Advancing to step 3:
If we divide 661 by 77, we get 8 and a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 616 from 661, we get 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 77

Step 4:
When dividing 458 by 77, we get 5 with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 73 after subtracting 385 from 458.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 77

Let's proceed to step 5:
If we divide 737 by 77, we get 9 and a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 859.0
If we take 693 away from 737, we end up with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 77

Let's proceed to step 6:
77 goes into 448 5 times with a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 8595.0
If we subtract 385 from 448, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
If we divide 630 by 77, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8595.8
If we take 616 away from 630, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 77, we get 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 8595.81
The remainder is 63 after subtracting 77 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
If we divide 630 by 77, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 8595.818
Deduct 616 from 630 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
140 divided by 77 is 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 8595.8181
If we subtract 77 from 140, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 11:
630 divided by 77 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 8595.81818
The remainder is 14 after subtracting 616 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
140 divided by 77 is 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 8595.818181
Deduct 77 from 140 and we're left 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.

Going ahead to step 13:
630 divided by 77 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8595.8181818
Subtracting 616 from 630 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 77 is 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 8595.81818181
Deduct 77 from 140 and we're left 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.

The final outcome is 8595.81818181, with a leftover of 6.3e-08.
