55346686 divided by 66 
Let's see how many times 66 fits into 55346686.

Advancing to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 66

Moving on to step 2:
66 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 66

Let's proceed to step 3:
If we divide 553 by 66, we get 8 and a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 8.0

Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 66

On to step 4:
The number 66 fits into 254 3 times, leaving a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we take 198 away from 254, we end up with 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 66

Advancing to step 5:
The number 66 fits into 566 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 838.0
Subtract 528 from 566 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 66

Let's proceed to step 6:
When dividing 386 by 66, we get 5 with a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 8385.0
Deduct 330 from 386 and we're left with 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 66

Advancing to step 7:
66 goes into 568 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 83858.0
Deduct 528 from 568 and we're left with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 66

On to step 8:
66 goes into 406 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 838586.0
If we subtract 396 from 406, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The next digit of our result is 1. 
Result so far: 838586.1
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
66 goes into 340 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 838586.15
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
100 divided by 66 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 838586.151
If we take 66 away from 100, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
If we divide 340 by 66, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 838586.1515
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
66 can be fit into 100 1 times, resulting in a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 838586.15151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
When dividing 340 by 66, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 838586.151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 838586.1515151
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 16:
66 goes into 340 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 838586.15151515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 838586.15151515 with a balance of 1e-08.
