We look at the division of 91373307 by 215 
Our goal is to divide 91373307 by 215.

Step 1:
215 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 215

Let's proceed to step 2:
215 can be fit into 91 0 times, resulting in a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 215

Let's proceed to step 3:
The number 215 fits into 913 4 times, leaving a remainder of 53.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 860 from 913 and we're left with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 215

Moving on to step 4:
If we divide 537 by 215, we get 2 and a remainder of 107.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 107 after subtracting 430 from 537.
Append the next digit (3) from the dividend to 107 and continue with: 1073 / 215

Advancing to step 5:
1073 divided by 215 is 4 with a remainder of 213.
The next digit of our result is 4. 
Result so far: 424.0
Subtract 860 from 1073 to get 213.
Append the next digit (3) from the dividend to 213 and continue with: 2133 / 215

On to step 6:
The number 215 fits into 2133 9 times, leaving a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 4249.0
Subtract 1935 from 2133 to get 198.
Append the next digit (0) from the dividend to 198 and continue with: 1980 / 215

On to step 7:
215 goes into 1980 9 times with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 42499.0
Subtract 1935 from 1980 to get 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 215

Moving on to step 8:
The number 215 fits into 457 2 times, leaving a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 424992.0
If we take 430 away from 457, 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.

Let's proceed to step 9:
The number 215 fits into 270 1 times, leaving a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 424992.1
Subtract 215 from 270 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
If we divide 550 by 215, we get 2 and a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 424992.12
If we take 430 away from 550, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
215 goes into 1200 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 424992.125
Deduct 1075 from 1200 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
215 goes into 1250 5 times with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 424992.1255
If we take 1075 away from 1250, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

In conclusion, the division gives 424992.1255 with a balance of 0.00175.
