Let's divide 131621 by 91
Let's see how many times 91 fits into 131621.

Let's proceed to step 1:
When dividing 1 by 91, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 91

Step 2:
The number 91 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 91

Let's proceed to step 3:
When dividing 131 by 91, we get 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 91 from 131 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 91

On to step 4:
When dividing 406 by 91, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 364 away from 406, we end up with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 91

Step 5:
The number 91 fits into 422 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 144.0
Deduct 364 from 422 and we're left with 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 91

Moving on to step 6:
91 goes into 581 6 times with a remainder of 35.
The next digit of our result is 6. 
Result so far: 1446.0
Subtracting 546 from 581 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
91 goes into 350 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 1446.3
Subtracting 273 from 350 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 8:
770 divided by 91 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 1446.38
If we subtract 728 from 770, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
91 can be fit into 420 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 1446.384
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
The number 91 fits into 560 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 1446.3846
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 91 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1446.38461
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
The number 91 fits into 490 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1446.384615
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
If we divide 350 by 91, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 1446.3846153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
The number 91 fits into 770 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 1446.38461538
If we take 728 away from 770, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 1446.38461538 with a remaining 4.2e-08.
