We're dividing 215400 by 91 
Our goal is to divide 215400 by 91.

Going ahead to step 1:
91 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 91

Going ahead to step 2:
21 divided by 91 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 91

Let's proceed to step 3:
The number 91 fits into 215 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 182 away from 215, we end up with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 91

Moving on to step 4:
When dividing 334 by 91, we get 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 61 after subtracting 273 from 334.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 91

Advancing to step 5:
91 can be fit into 610 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 236.0
If we subtract 546 from 610, we get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 91

Step 6:
When dividing 640 by 91, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2367.0
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
91 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2367.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 91 fits into 300 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 2367.03
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
91 goes into 270 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 2367.032
Deduct 182 from 270 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
880 divided by 91 is 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 2367.0329
Subtracting 819 from 880 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
91 can be fit into 610 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 2367.03296
Subtract 546 from 610 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
91 can be fit into 640 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 2367.032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
91 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2367.032967
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
91 goes into 300 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 2367.03296703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 2367.03296703 with a remainder of 2.7e-08.
