81888732 ÷ 680 
We're looking to find how many times 680 goes into 81888732.

Step 1:
When dividing 8 by 680, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 680

Advancing to step 2:
If we divide 81 by 680, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 680

Moving on to step 3:
680 can be fit into 818 1 times, resulting in a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 680 from 818, we get 138.
Append the next digit (8) from the dividend to 138 and continue with: 1388 / 680

Step 4:
1388 divided by 680 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1360 from 1388, we get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 680

On to step 5:
680 can be fit into 288 0 times, resulting in a remainder of 288.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtracting 0 from 288 leaves us with 288.
Include the next digit (7) from the dividend after 288, then repeat: 2887 / 680

Moving on to step 6:
The number 680 fits into 2887 4 times, leaving a remainder of 167.
Use 4 as the next digit of our solution. 
Result so far: 1204.0
Deduct 2720 from 2887 and we're left with 167.
Take the next digit (3) from the dividend and append it to 167, then repeat: 1673 / 680

Advancing to step 7:
The number 680 fits into 1673 2 times, leaving a remainder of 313.
Record the quotient 2 as the next digit in the result. 
Result so far: 12042.0
Deduct 1360 from 1673 and we're left with 313.
Fetch the next digit (2) from the dividend, attach it to 313 and continue: 3132 / 680

On to step 8:
3132 divided by 680 is 4 with a remainder of 412.
Use 4 as the next digit of our solution. 
Result so far: 120424.0
Deduct 2720 from 3132 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 9:
If we divide 4120 by 680, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 120424.6
Subtracting 4080 from 4120 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.

Moving on to step 10:
680 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 120424.6
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
680 can be fit into 4000 5 times, resulting in a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 120424.605
Subtract 3400 from 4000 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
If we divide 6000 by 680, we get 8 and a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 120424.6058
Subtract 5440 from 6000 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
5600 divided by 680 is 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 120424.60588
Subtracting 5440 from 5600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 120424.60588 with a remaining 0.00016.
