91431049 divided by 326 
We want to figure out the number of times 91431049 can be divided by 326.

On to step 1:
If we divide 9 by 326, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 326

Let's proceed to step 2:
If we divide 91 by 326, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Fetch the next digit (4) from the dividend, attach it to 91 and continue: 914 / 326

Step 3:
914 divided by 326 is 2 with a remainder of 262.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 652 from 914 to get 262.
Grab the next digit (3) from the dividend, add it to 262, then carry on: 2623 / 326

Let's proceed to step 4:
326 goes into 2623 8 times with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 15 after subtracting 2608 from 2623.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 326

Let's proceed to step 5:
326 can be fit into 151 0 times, resulting in a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtract 0 from 151 to get 151.
Include the next digit (0) from the dividend after 151, then repeat: 1510 / 326

Going ahead to step 6:
When dividing 1510 by 326, we get 4 with a remainder of 206.
Put 4 as the next digit of the answer. 
Result so far: 2804.0
The remainder is 206 after subtracting 1304 from 1510.
Take the next digit (4) from the dividend and append it to 206, then repeat: 2064 / 326

Going ahead to step 7:
326 can be fit into 2064 6 times, resulting in a remainder of 108.
Put 6 as the next digit of the answer. 
Result so far: 28046.0
Subtracting 1956 from 2064 leaves us with 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 326

Step 8:
The number 326 fits into 1089 3 times, leaving a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 280463.0
Subtracting 978 from 1089 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
The number 326 fits into 1110 3 times, leaving a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 280463.3
The remainder is 132 after subtracting 978 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
If we divide 1320 by 326, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 280463.34
The remainder is 16 after subtracting 1304 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 326 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 280463.34
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
326 can be fit into 1600 4 times, resulting in a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 280463.3404
If we subtract 1304 from 1600, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 13:
The number 326 fits into 2960 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 280463.34049
The remainder is 26 after subtracting 2934 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
260 divided by 326 is 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 280463.34049
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 15:
2600 divided by 326 is 7 with a remainder of 318.
The next digit of our result is 7. 
Result so far: 280463.3404907
Deduct 2282 from 2600 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 16:
326 goes into 3180 9 times with a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 280463.34049079
Subtracting 2934 from 3180 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

In conclusion, the division gives 280463.34049079 with a balance of 2.46e-07.
