We look at the division of 845424 by 77 
Let's see how many times 77 fits into 845424.

Let's proceed to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 77

Going ahead to step 2:
77 can be fit into 84 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 77 from 84 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 77

On to step 3:
77 goes into 75 0 times with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 75, we end up with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 77

On to step 4:
754 divided by 77 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtract 693 from 754 to get 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 77

On to step 5:
612 divided by 77 is 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 1097.0
If we subtract 539 from 612, we get 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 77

On to step 6:
The number 77 fits into 734 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 10979.0
Subtracting 693 from 734 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
When dividing 410 by 77, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10979.5
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
If we divide 250 by 77, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 10979.53
The remainder is 19 after subtracting 231 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
77 can be fit into 190 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 10979.532
If we subtract 154 from 190, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
360 divided by 77 is 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 10979.5324
Deduct 308 from 360 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
The number 77 fits into 520 6 times, leaving a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 10979.53246
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
77 can be fit into 580 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 10979.532467
Subtracting 539 from 580 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 13:
77 goes into 410 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10979.5324675
Subtract 385 from 410 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
77 goes into 250 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 10979.53246753
Deduct 231 from 250 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 10979.53246753 and a remainder of 1.9e-08.
