We look at the division of 103249 by 77 
Let's see how many times 77 fits into 103249.

Let's proceed to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 77

On to step 2:
77 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 77

Let's proceed to step 3:
If we divide 103 by 77, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 77 from 103 and we're left with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 77

Going ahead to step 4:
When dividing 262 by 77, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 231 from 262 to get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 77

On to step 5:
If we divide 314 by 77, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Subtract 308 from 314 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 77

Step 6:
77 can be fit into 69 0 times, resulting in a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 1340.0
If we take 0 away from 69, we end up 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.

Moving on to step 7:
77 goes into 690 8 times with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 1340.8
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.

Going ahead to step 8:
When dividing 740 by 77, we get 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 1340.89
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.

Advancing to step 9:
If we divide 470 by 77, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1340.896
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.

On to step 10:
The number 77 fits into 80 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1340.8961
If we take 77 away from 80, we end up with 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 11:
If we divide 30 by 77, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1340.8961
Deduct 0 from 30 and we're left with 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 12:
300 divided by 77 is 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 1340.896103
If we take 231 away from 300, we end up 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 13:
The number 77 fits into 690 8 times, leaving a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 1340.8961038
Subtracting 616 from 690 leaves us 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.

Advancing to step 14:
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: 1340.89610389
Deduct 693 from 740 and we're left 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.

The final outcome is 1340.89610389, with a leftover of 4.7e-08.
