Let's divide 91255541 by 215
Our goal is to divide 91255541 by 215.

Advancing to step 1:
215 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 215

On to step 2:
The number 215 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 215

Let's proceed to step 3:
912 divided by 215 is 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 4.0
If we take 860 away from 912, we end up with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 215

Step 4:
The number 215 fits into 525 2 times, leaving a remainder of 95.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 430 from 525 to get 95.
Grab the next digit (5) from the dividend, add it to 95, then carry on: 955 / 215

Step 5:
215 goes into 955 4 times with a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 424.0
Subtract 860 from 955 to get 95.
Bring next digit (5) of the dividend behind the 95 and repeat the process: 955 / 215

On to step 6:
If we divide 955 by 215, we get 4 and a remainder of 95.
Put 4 as the next digit of the answer. 
Result so far: 4244.0
If we take 860 away from 955, we end up with 95.
Bring next digit (4) of the dividend behind the 95 and repeat the process: 954 / 215

Moving on to step 7:
When dividing 954 by 215, we get 4 with a remainder of 94.
The next digit of our result is 4. 
Result so far: 42444.0
If we subtract 860 from 954, we get 94.
Append the next digit (1) from the dividend to 94 and continue with: 941 / 215

Going ahead to step 8:
941 divided by 215 is 4 with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 424444.0
Subtracting 860 from 941 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
810 divided by 215 is 3 with a remainder of 165.
The next digit of our result is 3. 
Result so far: 424444.3
The remainder is 165 after subtracting 645 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 10:
The number 215 fits into 1650 7 times, leaving a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 424444.37
Deduct 1505 from 1650 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 11:
The number 215 fits into 1450 6 times, leaving a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 424444.376
Deduct 1290 from 1450 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
215 can be fit into 1600 7 times, resulting in a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 424444.3767
If we take 1505 away from 1600, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 13:
The number 215 fits into 950 4 times, leaving a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 424444.37674
The remainder is 90 after subtracting 860 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
215 goes into 900 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 424444.376744
Subtract 860 from 900 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 424444.376744 and a remainder of 4e-06.
