We divide 154430 by 77
We're looking to find how many times 77 goes into 154430.

Going ahead to step 1:
The number 77 fits into 1 0 times, leaving 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.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 77

Let's proceed to step 2:
77 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 77

Let's proceed to step 3:
If we divide 154 by 77, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 154 from 154 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 77

Moving on to step 4:
If we divide 4 by 77, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 77

Going ahead to step 5:
The number 77 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 200.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 77

Step 6:
The number 77 fits into 430 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2005.0
If we take 385 away from 430, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
77 can be fit into 450 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 2005.5
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.

Step 8:
77 can be fit into 650 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 2005.58
The remainder is 34 after subtracting 616 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
77 goes into 340 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 2005.584
Deduct 308 from 340 and we're left 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.

Going ahead to step 10:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 2005.5844
Subtracting 308 from 320 leaves us 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 2005.5844 with a remaining 0.00012.
