We're dividing 844521 by 77 
Let's see how many times 77 fits into 844521.

Let's proceed to step 1:
8 divided by 77 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 77

Moving on to step 2:
77 goes into 84 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 77 from 84, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 77

Going ahead to step 3:
74 divided by 77 is 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 74 to get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 77

Moving on to step 4:
When dividing 745 by 77, we get 9 with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtract 693 from 745 to get 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 77

Moving on to step 5:
77 goes into 522 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 1096.0
Subtracting 462 from 522 leaves us with 60.
Fetch the next digit (1) from the dividend, attach it to 60 and continue: 601 / 77

On to step 6:
77 goes into 601 7 times with a remainder of 62.
The next digit of our result is 7. 
Result so far: 10967.0
If we subtract 539 from 601, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10967.8
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 77, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 10967.8
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 77 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10967.805
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 10967.8051
If we take 77 away from 150, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 11:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 10967.80519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
370 divided by 77 is 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 10967.805194
If we subtract 308 from 370, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
77 can be fit into 620 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 10967.8051948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 77 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10967.8051948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 10967.8051948, with a leftover of 4e-08.
