We're dividing 134430 by 77 
We're looking to find how many times 77 goes into 134430.

Going ahead to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 77

Step 2:
The number 77 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 77

Let's proceed to step 3:
134 divided by 77 is 1 with a remainder of 57.
The next digit of our result is 1. 
Result so far: 1.0
If we take 77 away from 134, we end up with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 77

Advancing to step 4:
77 goes into 574 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 539 from 574 leaves us with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 77

Advancing to step 5:
The number 77 fits into 353 4 times, leaving a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Subtracting 308 from 353 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 77

On to step 6:
If we divide 450 by 77, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 1745.0
The remainder is 65 after subtracting 385 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
If we divide 650 by 77, we get 8 and a remainder of 34.
The next digit of our result is 8. 
Result so far: 1745.8
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 77 fits into 340 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 1745.84
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
77 can be fit into 320 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 1745.844
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 1745.844 with a remaining 0.0012.
