We look at the division of 66811555 by 168 
We want to figure out the number of times 66811555 can be divided by 168.

Advancing to step 1:
When dividing 6 by 168, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 168

Step 2:
168 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 168

On to step 3:
668 divided by 168 is 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 3.0
If we take 504 away from 668, we end up with 164.
Append the next digit (1) from the dividend to 164 and continue with: 1641 / 168

Advancing to step 4:
When dividing 1641 by 168, we get 9 with a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 1512 away from 1641, we end up with 129.
Take the next digit (1) from the dividend and append it to 129, then repeat: 1291 / 168

Step 5:
The number 168 fits into 1291 7 times, leaving a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
Subtract 1176 from 1291 to get 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 168

On to step 6:
When dividing 1155 by 168, we get 6 with a remainder of 147.
The next digit of our result is 6. 
Result so far: 3976.0
Subtracting 1008 from 1155 leaves us with 147.
Include the next digit (5) from the dividend after 147, then repeat: 1475 / 168

Going ahead to step 7:
168 can be fit into 1475 8 times, resulting in a remainder of 131.
Use 8 as the next digit of our solution. 
Result so far: 39768.0
If we subtract 1344 from 1475, we get 131.
Bring next digit (5) of the dividend behind the 131 and repeat the process: 1315 / 168

Let's proceed to step 8:
168 goes into 1315 7 times with a remainder of 139.
Record the quotient 7 as the next digit in the result. 
Result so far: 397687.0
The remainder is 139 after subtracting 1176 from 1315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 9:
When dividing 1390 by 168, we get 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 397687.8
Subtracting 1344 from 1390 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
When dividing 460 by 168, we get 2 with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 397687.82
The remainder is 124 after subtracting 336 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
1240 divided by 168 is 7 with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 397687.827
If we subtract 1176 from 1240, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
The number 168 fits into 640 3 times, leaving a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 397687.8273
Subtract 504 from 640 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 13:
When dividing 1360 by 168, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 397687.82738
If we take 1344 away from 1360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 168 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 397687.82738
If we take 0 away from 160, we end up 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.

Advancing to step 15:
The number 168 fits into 1600 9 times, leaving a remainder of 88.
The next digit of our result is 9. 
Result so far: 397687.8273809
Deduct 1512 from 1600 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 16:
When dividing 880 by 168, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 397687.82738095
Deduct 840 from 880 and we're left 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.

The quotient of the division is 397687.82738095, and the remainder is 4e-08.
