We divide 66249936 by 91
We want to divide 66249936 by 91.

Step 1:
91 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 91

Moving on 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 (2) from the dividend and append it to 66, then repeat: 662 / 91

Advancing to step 3:
91 goes into 662 7 times with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 637 from 662 to get 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 91

Let's proceed to step 4:
The number 91 fits into 254 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 182 from 254 and we're left with 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 91

Let's proceed to step 5:
When dividing 729 by 91, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 728.0
If we take 728 away from 729, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 91

Let's proceed to step 6:
If we divide 19 by 91, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 7280.0
If we subtract 0 from 19, we get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 91

Going ahead to step 7:
91 goes into 193 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 72802.0
Subtract 182 from 193 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 91

Moving on to step 8:
116 divided by 91 is 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 728021.0
Subtract 91 from 116 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 91, we get 2 and a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 728021.2
If we subtract 182 from 250, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
The number 91 fits into 680 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 728021.27
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
When dividing 430 by 91, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 728021.274
Subtracting 364 from 430 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
91 goes into 660 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 728021.2747
Subtract 637 from 660 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
91 goes into 230 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 728021.27472
If we take 182 away from 230, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
91 goes into 480 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 728021.274725
Subtracting 455 from 480 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 15:
If we divide 250 by 91, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 728021.2747252
If we subtract 182 from 250, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
91 can be fit into 680 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 728021.27472527
Deduct 637 from 680 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 728021.27472527 and a remainder of 4.3e-08.
