We're dividing 84427776 by 686 
We want to figure out the number of times 84427776 can be divided by 686.

Advancing to step 1:
If we divide 8 by 686, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 686

Moving on to step 2:
When dividing 84 by 686, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 686

Going ahead to step 3:
686 can be fit into 844 1 times, resulting in a remainder of 158.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 686 away from 844, we end up with 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 686

Moving on to step 4:
686 goes into 1582 2 times with a remainder of 210.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1372 from 1582 leaves us with 210.
Take the next digit (7) from the dividend and append it to 210, then repeat: 2107 / 686

Going ahead to step 5:
686 goes into 2107 3 times with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
The remainder is 49 after subtracting 2058 from 2107.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 686

Moving on to step 6:
The number 686 fits into 497 0 times, leaving a remainder of 497.
Record the quotient 0 as the next digit in the result. 
Result so far: 1230.0
If we subtract 0 from 497, we get 497.
Append the next digit (7) from the dividend to 497 and continue with: 4977 / 686

Moving on to step 7:
686 goes into 4977 7 times with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 12307.0
If we subtract 4802 from 4977, we get 175.
Fetch the next digit (6) from the dividend, attach it to 175 and continue: 1756 / 686

Going ahead to step 8:
686 can be fit into 1756 2 times, resulting in a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 123072.0
The remainder is 384 after subtracting 1372 from 1756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 9:
If we divide 3840 by 686, we get 5 and a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 123072.5
Deduct 3430 from 3840 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
686 can be fit into 4100 5 times, resulting in a remainder of 670.
Put 5 as the next digit of the answer. 
Result so far: 123072.55
Subtract 3430 from 4100 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

The quotient of the division is 123072.55, and the remainder is 0.67.
