231099 divided by 77 
Let's see how many times 77 fits into 231099.

Going ahead to step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 77

Moving on to step 2:
The number 77 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 77

Going ahead to step 3:
77 goes into 231 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 231 away from 231, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 77

On to step 4:
When dividing 0 by 77, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 77

On to step 5:
77 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
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 6:
The number 77 fits into 99 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 3001.0
If we take 77 away from 99, 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.

Let's proceed to step 7:
77 goes into 220 2 times with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 3001.2
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 8:
The number 77 fits into 660 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 3001.28
Subtract 616 from 660 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 77 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 3001.285
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.

Let's proceed to step 10:
550 divided by 77 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 3001.2857
If we take 539 away from 550, we end up 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 11:
When dividing 110 by 77, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 3001.28571
Subtract 77 from 110 to get 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 12:
If we divide 330 by 77, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 3001.285714
Subtract 308 from 330 to 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.

Moving on to step 13:
When dividing 220 by 77, we get 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 3001.2857142
The remainder is 66 after subtracting 154 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
If we divide 660 by 77, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 3001.28571428
Deduct 616 from 660 and we're left 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.

The final outcome is 3001.28571428, with a leftover of 4.4e-08.
