We're dividing 402986 by 66 
We're looking to find how many times 66 goes into 402986.

Step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 66

Going ahead to step 2:
66 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 66

Let's proceed to step 3:
66 goes into 402 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 396 away from 402, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 66

Going ahead to step 4:
66 can be fit into 69 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 66 from 69 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 66

Moving on to step 5:
If we divide 38 by 66, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 610.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 66

Going ahead to step 6:
The number 66 fits into 386 5 times, leaving a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 6105.0
Subtract 330 from 386 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 6105.8
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
The number 66 fits into 320 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 6105.84
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
The number 66 fits into 560 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 6105.848
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 66, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 6105.8484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
66 can be fit into 560 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 6105.84848
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
66 can be fit into 320 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 6105.848484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
66 goes into 560 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 6105.8484848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
When dividing 320 by 66, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 6105.84848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 6105.84848484, with a leftover of 5.6e-08.
