124779 ÷ 77 
We want to divide 124779 by 77.

Step 1:
1 divided by 77 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 77

Advancing to step 2:
The number 77 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 77

Advancing to step 3:
77 can be fit into 124 1 times, resulting in a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 124, we end up with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 77

Step 4:
When dividing 477 by 77, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 462 from 477 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 77

Let's proceed to step 5:
157 divided by 77 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 162.0
Deduct 154 from 157 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 77

On to step 6:
When dividing 39 by 77, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 1620.0
Deduct 0 from 39 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
If we divide 390 by 77, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 1620.5
The remainder is 5 after subtracting 385 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 77 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 1620.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 77, we get 6 and a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 1620.506
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
When dividing 380 by 77, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 1620.5064
Subtracting 308 from 380 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
If we divide 720 by 77, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 1620.50649
The remainder is 27 after subtracting 693 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
When dividing 270 by 77, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 1620.506493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
The number 77 fits into 390 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1620.5064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
When dividing 50 by 77, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1620.5064935
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 1620.5064935, with a leftover of 5e-08.
