84878102 ÷ 681 
Let's see how many times 681 fits into 84878102.

On to step 1:
The number 681 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 681

Step 2:
681 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 681

Going ahead to step 3:
681 can be fit into 848 1 times, resulting in a remainder of 167.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 681 from 848 and we're left with 167.
Fetch the next digit (7) from the dividend, attach it to 167 and continue: 1677 / 681

Going ahead to step 4:
1677 divided by 681 is 2 with a remainder of 315.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1362 from 1677, we get 315.
Append the next digit (8) from the dividend to 315 and continue with: 3158 / 681

Advancing to step 5:
If we divide 3158 by 681, we get 4 and a remainder of 434.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 2724 away from 3158, we end up with 434.
Append the next digit (1) from the dividend to 434 and continue with: 4341 / 681

On to step 6:
The number 681 fits into 4341 6 times, leaving a remainder of 255.
The number 6 becomes the next digit in our result. 
Result so far: 1246.0
If we subtract 4086 from 4341, we get 255.
Include the next digit (0) from the dividend after 255, then repeat: 2550 / 681

Let's proceed to step 7:
2550 divided by 681 is 3 with a remainder of 507.
The next digit of our result is 3. 
Result so far: 12463.0
If we subtract 2043 from 2550, we get 507.
Bring next digit (2) of the dividend behind the 507 and repeat the process: 5072 / 681

Advancing to step 8:
The number 681 fits into 5072 7 times, leaving a remainder of 305.
Write down 7 as next digit of the result. 
Result so far: 124637.0
Subtract 4767 from 5072 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
If we divide 3050 by 681, we get 4 and a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 124637.4
If we subtract 2724 from 3050, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
The number 681 fits into 3260 4 times, leaving a remainder of 536.
The number 4 becomes the next digit in our result. 
Result so far: 124637.44
If we take 2724 away from 3260, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The final outcome is 124637.44, with a leftover of 0.536.
