We're dividing 985640 by 77 
Our goal is to divide 985640 by 77.

Moving on to step 1:
77 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 77

Moving on to step 2:
The number 77 fits into 98 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 77 from 98 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 77

Advancing to step 3:
77 can be fit into 215 2 times, resulting in a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 154 from 215 and we're left with 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 77

Let's proceed to step 4:
616 divided by 77 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 616 from 616 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 77

Moving on to step 5:
77 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 1280.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 77

Step 6:
77 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 12800.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
When dividing 400 by 77, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12800.5
Subtract 385 from 400 to 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 8:
150 divided by 77 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 12800.51
If we take 77 away from 150, we end up with 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 9:
When dividing 730 by 77, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 12800.519
Subtract 693 from 730 to 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.

Step 10:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 12800.5194
If we subtract 308 from 370, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
77 can be fit into 620 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12800.51948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 77 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 12800.51948
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
When dividing 400 by 77, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12800.5194805
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
150 divided by 77 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 12800.51948051
If we subtract 77 from 150, we 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.

The final result is 12800.51948051 with a remainder of 7.3e-08.
