Let's divide 398148 by 66
We're looking to find how many times 66 goes into 398148.

Moving on to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 66

Going ahead to step 2:
66 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 66

Let's proceed to step 3:
66 can be fit into 398 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 396 from 398 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 66

Let's proceed to step 4:
66 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 66

Advancing to step 5:
If we divide 214 by 66, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 603.0
If we take 198 away from 214, we end up with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 66

Advancing to step 6:
If we divide 168 by 66, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 6032.0
If we subtract 132 from 168, 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 7:
When dividing 360 by 66, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 6032.5
Subtracting 330 from 360 leaves us 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.

Going ahead to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 6032.54
Deduct 264 from 300 and we're left 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.

Advancing to step 9:
If we divide 360 by 66, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 6032.545
If we subtract 330 from 360, 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 10:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 6032.5454
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.

Going ahead to step 11:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 6032.54545
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 12:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 6032.545454
If we take 264 away from 300, we end up 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.

On to step 13:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 6032.5454545
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.

Moving on to step 14:
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: 6032.54545454
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.

In conclusion, the division gives 6032.54545454 with a balance of 3.6e-08.
