We look at the division of 125397 by 66 
Let's see how many times 66 fits into 125397.

Moving on to step 1:
1 divided by 66 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 66

Let's proceed to step 2:
The number 66 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 66

Going ahead to step 3:
66 can be fit into 125 1 times, resulting in a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 66 from 125 leaves us with 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 66

Advancing to step 4:
The number 66 fits into 593 8 times, leaving a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 528 away from 593, we end up with 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 66

Let's proceed to step 5:
The number 66 fits into 659 9 times, leaving a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we take 594 away from 659, we end up with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 66

Moving on to step 6:
When dividing 657 by 66, we get 9 with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 1899.0
Deduct 594 from 657 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
When dividing 630 by 66, we get 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 1899.9
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 66 fits into 360 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 1899.95
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 1899.954
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.

Going ahead to step 10:
The number 66 fits into 360 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 1899.9545
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.

Advancing to step 11:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1899.95454
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.

Going ahead to step 12:
66 goes into 360 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1899.954545
Subtract 330 from 360 to 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.

Let's proceed to step 13:
300 divided by 66 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1899.9545454
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.

Advancing to step 14:
When dividing 360 by 66, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1899.95454545
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.

In conclusion, the division gives 1899.95454545 with a balance of 3e-08.
