We look at the division of 87379 by 77 
We're looking to find how many times 77 goes into 87379.

Step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 77

On to step 2:
87 divided by 77 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we take 77 away from 87, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 77

Moving on to step 3:
77 goes into 103 1 times with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 77 from 103 and we're left with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 77

Advancing to step 4:
The number 77 fits into 267 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 113.0
The remainder is 36 after subtracting 231 from 267.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 77

Moving on to step 5:
77 goes into 369 4 times with a remainder of 61.
The next digit of our result is 4. 
Result so far: 1134.0
Subtracting 308 from 369 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 6:
The number 77 fits into 610 7 times, leaving a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 1134.7
Subtracting 539 from 610 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
If we divide 710 by 77, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 1134.79
Subtracting 693 from 710 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
77 goes into 170 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1134.792
Subtracting 154 from 170 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
When dividing 160 by 77, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 1134.7922
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 1134.7922 with a remaining 6e-05.
