84463100 ÷ 680 
Our goal is to divide 84463100 by 680.

Going ahead to step 1:
8 divided by 680 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 680

Advancing to step 2:
When dividing 84 by 680, 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.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 680

Moving on to step 3:
680 can be fit into 844 1 times, resulting in a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 164 after subtracting 680 from 844.
Fetch the next digit (6) from the dividend, attach it to 164 and continue: 1646 / 680

Going ahead to step 4:
680 goes into 1646 2 times with a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 286 after subtracting 1360 from 1646.
Append the next digit (3) from the dividend to 286 and continue with: 2863 / 680

Step 5:
If we divide 2863 by 680, we get 4 and a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 2720 from 2863 to get 143.
Grab the next digit (1) from the dividend, add it to 143, then carry on: 1431 / 680

Advancing to step 6:
The number 680 fits into 1431 2 times, leaving a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 1242.0
Subtracting 1360 from 1431 leaves us with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 680

Going ahead to step 7:
680 goes into 710 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 12421.0
If we subtract 680 from 710, we get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 680

Advancing to step 8:
300 divided by 680 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 124210.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 9:
680 can be fit into 3000 4 times, resulting in a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 124210.4
Subtracting 2720 from 3000 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
680 can be fit into 2800 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 124210.44
If we take 2720 away from 2800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 124210.44 with a remainder of 0.08.
