We look at the division of 137449 by 77 
We're looking to find how many times 77 goes into 137449.

On to step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 77

Moving on to step 2:
77 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 77

Advancing to step 3:
77 goes into 137 1 times with a remainder of 60.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 77 from 137 and we're left with 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 77

On to step 4:
If we divide 604 by 77, we get 7 and a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 539 from 604 and we're left with 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 77

On to step 5:
The number 77 fits into 654 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we take 616 away from 654, we end up with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 77

On to step 6:
The number 77 fits into 389 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1785.0
Deduct 385 from 389 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
77 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 1785.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 77, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1785.05
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1785.051
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 10:
If we divide 730 by 77, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 1785.0519
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 1785.05194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
The number 77 fits into 620 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 1785.051948
If we subtract 616 from 620, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
If we divide 40 by 77, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1785.051948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
When dividing 400 by 77, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1785.05194805
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 1785.05194805 with a remainder of 1.5e-08.
