We look at the division of 125469 by 66 
We want to divide 125469 by 66.

Advancing to step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 66

Going ahead to step 2:
The number 66 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 66

Advancing to step 3:
125 divided by 66 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 59 after subtracting 66 from 125.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 66

Step 4:
594 divided by 66 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 0 after subtracting 594 from 594.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 66

Advancing to step 5:
The number 66 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 190.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 66

On to step 6:
If we divide 69 by 66, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1901.0
Subtract 66 from 69 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 66 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1901.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 66 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1901.04
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1901.045
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 66 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1901.0454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
When dividing 360 by 66, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1901.04545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
66 goes into 300 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1901.045454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1901.0454545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1901.04545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 1901.04545454, with a leftover of 3.6e-08.
