66355 ÷ 91 
Our goal is to divide 66355 by 91.

Let's proceed to step 1:
91 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 91

Going ahead to step 2:
66 divided by 91 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 91

Step 3:
91 goes into 663 7 times with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 637 from 663 and we're left with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 91

Advancing to step 4:
When dividing 265 by 91, we get 2 with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 72.0
Deduct 182 from 265 and we're left with 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 91

Moving on to step 5:
91 goes into 835 9 times with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 729.0
Subtracting 819 from 835 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 6:
When dividing 160 by 91, we get 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 729.1
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
91 goes into 690 7 times with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 729.17
Deduct 637 from 690 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 729.175
If we subtract 455 from 530, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
750 divided by 91 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 729.1758
Deduct 728 from 750 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
The number 91 fits into 220 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 729.17582
Subtract 182 from 220 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
When dividing 380 by 91, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 729.175824
If we take 364 away from 380, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
91 can be fit into 160 1 times, resulting in a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 729.1758241
If we take 91 away from 160, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 13:
690 divided by 91 is 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 729.17582417
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 729.17582417 with a remainder of 5.3e-08.
