Let's divide 102379 by 77
We want to divide 102379 by 77.

On to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 77

Let's proceed to step 2:
When dividing 10 by 77, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 77

Moving on to step 3:
102 divided by 77 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 77 from 102 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 77

On to step 4:
If we divide 253 by 77, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 231 from 253 leaves us with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 77

Let's proceed to step 5:
227 divided by 77 is 2 with a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtract 154 from 227 to get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 77

Let's proceed to step 6:
77 goes into 739 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 1329.0
If we take 693 away from 739, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
If we divide 460 by 77, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1329.5
If we take 385 away from 460, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 8:
750 divided by 77 is 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 1329.59
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
77 can be fit into 570 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1329.597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
If we divide 310 by 77, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1329.5974
Subtracting 308 from 310 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
77 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1329.5974
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
When dividing 200 by 77, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 1329.597402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
When dividing 460 by 77, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1329.5974025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
When dividing 750 by 77, we get 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 1329.59740259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 1329.59740259 with a remainder of 5.7e-08.
