We look at the division of 993143 by 77 
We want to figure out the number of times 993143 can be divided by 77.

Let's proceed to step 1:
9 divided by 77 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 77

Advancing to step 2:
77 goes into 99 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 77 from 99 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 77

Going ahead to step 3:
77 can be fit into 223 2 times, resulting in a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 154 away from 223, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 77

Moving on to step 4:
691 divided by 77 is 8 with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we subtract 616 from 691, we get 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 77

Moving on to step 5:
754 divided by 77 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 1289.0
Subtracting 693 from 754 leaves us with 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 77

Going ahead to step 6:
613 divided by 77 is 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 12897.0
Deduct 539 from 613 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
740 divided by 77 is 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 12897.9
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
When dividing 470 by 77, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 12897.96
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
77 goes into 80 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 12897.961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
When dividing 30 by 77, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 12897.961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 77, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 12897.96103
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
77 goes into 690 8 times with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 12897.961038
If we take 616 away from 690, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 12897.9610389
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 14:
77 goes into 470 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12897.96103896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 12897.96103896 and a remainder of 8e-09.
