Let's see how many times 477 fits into 66459748.

Advancing to step 1:
477 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 477

Advancing to step 2:
66 divided by 477 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 477

Step 3:
If we divide 664 by 477, we get 1 and a remainder of 187.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 477 from 664 to get 187.
Grab the next digit (5) from the dividend, add it to 187, then carry on: 1875 / 477

Let's proceed to step 4:
477 can be fit into 1875 3 times, resulting in a remainder of 444.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1431 away from 1875, we end up with 444.
Grab the next digit (9) from the dividend, add it to 444, then carry on: 4449 / 477

Step 5:
477 can be fit into 4449 9 times, resulting in a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we take 4293 away from 4449, we end up with 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 477

Step 6:
477 goes into 1567 3 times with a remainder of 136.
The next digit of our result is 3. 
Result so far: 1393.0
The remainder is 136 after subtracting 1431 from 1567.
Fetch the next digit (4) from the dividend, attach it to 136 and continue: 1364 / 477

Going ahead to step 7:
The number 477 fits into 1364 2 times, leaving a remainder of 410.
The next digit of our result is 2. 
Result so far: 13932.0
Deduct 954 from 1364 and we're left with 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 477

Step 8:
4108 divided by 477 is 8 with a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 139328.0
Subtract 3816 from 4108 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
477 can be fit into 2920 6 times, resulting in a remainder of 58.
The next digit of our result is 6. 
Result so far: 139328.6
Deduct 2862 from 2920 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
477 goes into 580 1 times with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 139328.61
Deduct 477 from 580 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 11:
If we divide 1030 by 477, we get 2 and a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 139328.612
Subtract 954 from 1030 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
The number 477 fits into 760 1 times, leaving a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 139328.6121
Subtract 477 from 760 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 13:
477 goes into 2830 5 times with a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 139328.61215
If we take 2385 away from 2830, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 14:
4450 divided by 477 is 9 with a remainder of 157.
Record the quotient 9 as the next digit in the result. 
Result so far: 139328.612159
The remainder is 157 after subtracting 4293 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 15:
1570 divided by 477 is 3 with a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 139328.6121593
Deduct 1431 from 1570 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 16:
1390 divided by 477 is 2 with a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 139328.61215932
If we subtract 954 from 1390, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

In conclusion, the division gives 139328.61215932 with a balance of 4.36e-07.
