Let's divide 681451 by 66
We want to divide 681451 by 66.

Step 1:
6 divided by 66 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 66

Advancing to step 2:
If we divide 68 by 66, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 68 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 66

Moving on to step 3:
66 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 66

Let's proceed to step 4:
If we divide 214 by 66, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 198 away from 214, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 66

Advancing to step 5:
66 can be fit into 165 2 times, resulting in a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 1032.0
If we subtract 132 from 165, we get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 66

Moving on to step 6:
66 goes into 331 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 10325.0
Subtract 330 from 331 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 66 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10325.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
66 goes into 100 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 10325.01
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 66, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10325.015
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
66 goes into 100 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 10325.0151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 66 fits into 340 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10325.01515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 10325.015151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
If we divide 340 by 66, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10325.0151515
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 66, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 10325.01515151
If we take 66 away from 100, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 10325.01515151, with a leftover of 3.4e-08.
