Let's divide 81301172 by 687
Our goal is to divide 81301172 by 687.

Advancing to step 1:
The number 687 fits into 8 0 times, leaving 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 687

Moving on to step 2:
If we divide 81 by 687, 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.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 687

Step 3:
If we divide 813 by 687, we get 1 and a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 687 from 813 and we're left with 126.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 687

Advancing to step 4:
687 can be fit into 1260 1 times, resulting in a remainder of 573.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 687 from 1260 and we're left with 573.
Bring next digit (1) of the dividend behind the 573 and repeat the process: 5731 / 687

Advancing to step 5:
If we divide 5731 by 687, we get 8 and a remainder of 235.
The next digit of our result is 8. 
Result so far: 118.0
The remainder is 235 after subtracting 5496 from 5731.
Include the next digit (1) from the dividend after 235, then repeat: 2351 / 687

Going ahead to step 6:
2351 divided by 687 is 3 with a remainder of 290.
Use 3 as the next digit of our solution. 
Result so far: 1183.0
If we subtract 2061 from 2351, we get 290.
Bring next digit (7) of the dividend behind the 290 and repeat the process: 2907 / 687

On to step 7:
687 goes into 2907 4 times with a remainder of 159.
Put 4 as the next digit of the answer. 
Result so far: 11834.0
Subtract 2748 from 2907 to get 159.
Grab the next digit (2) from the dividend, add it to 159, then carry on: 1592 / 687

On to step 8:
When dividing 1592 by 687, we get 2 with a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 118342.0
Subtracting 1374 from 1592 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
687 goes into 2180 3 times with a remainder of 119.
The next digit of our result is 3. 
Result so far: 118342.3
Subtracting 2061 from 2180 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 10:
When dividing 1190 by 687, we get 1 with a remainder of 503.
Write down 1 as next digit of the result. 
Result so far: 118342.31
The remainder is 503 after subtracting 687 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 11:
If we divide 5030 by 687, we get 7 and a remainder of 221.
The next digit of our result is 7. 
Result so far: 118342.317
Subtracting 4809 from 5030 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 12:
687 can be fit into 2210 3 times, resulting in a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 118342.3173
If we take 2061 away from 2210, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 13:
1490 divided by 687 is 2 with a remainder of 116.
The next digit of our result is 2. 
Result so far: 118342.31732
Deduct 1374 from 1490 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 14:
The number 687 fits into 1160 1 times, leaving a remainder of 473.
The number 1 becomes the next digit in our result. 
Result so far: 118342.317321
Subtracting 687 from 1160 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Step 15:
When dividing 4730 by 687, we get 6 with a remainder of 608.
Write down 6 as next digit of the result. 
Result so far: 118342.3173216
Subtracting 4122 from 4730 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 16:
6080 divided by 687 is 8 with a remainder of 584.
Write down 8 as next digit of the result. 
Result so far: 118342.31732168
Subtract 5496 from 6080 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

After the division, we end up with 118342.31732168 and a remainder of 5.84e-07.
