77769894 ÷ 154 
We want to figure out the number of times 77769894 can be divided by 154.

On to step 1:
154 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 154

Advancing to step 2:
154 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 154

Going ahead to step 3:
When dividing 777 by 154, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 770 from 777 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 154

On to step 4:
154 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 76 to get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 154

On to step 5:
154 can be fit into 769 4 times, resulting in a remainder of 153.
The next digit of our result is 4. 
Result so far: 504.0
If we take 616 away from 769, we end up with 153.
Bring next digit (8) of the dividend behind the 153 and repeat the process: 1538 / 154

Let's proceed to step 6:
154 can be fit into 1538 9 times, resulting in a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 5049.0
Deduct 1386 from 1538 and we're left with 152.
Bring next digit (9) of the dividend behind the 152 and repeat the process: 1529 / 154

Step 7:
If we divide 1529 by 154, we get 9 and a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 50499.0
The remainder is 143 after subtracting 1386 from 1529.
Grab the next digit (4) from the dividend, add it to 143, then carry on: 1434 / 154

Let's proceed to step 8:
If we divide 1434 by 154, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 504999.0
Deduct 1386 from 1434 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
If we divide 480 by 154, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 504999.3
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
When dividing 180 by 154, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 504999.31
If we take 154 away from 180, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
260 divided by 154 is 1 with a remainder of 106.
Record the quotient 1 as the next digit in the result. 
Result so far: 504999.311
If we take 154 away from 260, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 504999.311 with a balance of 0.0106.
