We divide 817419 by 66
Let's see how many times 66 fits into 817419.

Step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 66

Moving on to step 2:
If we divide 81 by 66, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 66 from 81, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 66

Going ahead to step 3:
The number 66 fits into 157 2 times, leaving a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 132 from 157 to get 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 66

Step 4:
The number 66 fits into 254 3 times, leaving a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we subtract 198 from 254, we get 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 66

Moving on to step 5:
66 goes into 561 8 times with a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 1238.0
The remainder is 33 after subtracting 528 from 561.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 66

Moving on to step 6:
When dividing 339 by 66, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 12385.0
If we take 330 away from 339, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 66, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 12385.1
Deduct 66 from 90 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
240 divided by 66 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12385.13
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
420 divided by 66 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 12385.136
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 66, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12385.1363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
420 divided by 66 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12385.13636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 12385.136363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
66 can be fit into 420 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 12385.1363636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
240 divided by 66 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 12385.13636363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 12385.13636363, with a leftover of 4.2e-08.
