902993 ÷ 91 
We want to figure out the number of times 902993 can be divided by 91.

Moving on to step 1:
9 divided by 91 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 91

Moving on to step 2:
If we divide 90 by 91, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 91

Step 3:
The number 91 fits into 902 9 times, leaving a remainder of 83.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 819 from 902 and we're left with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 91

Let's proceed to step 4:
If we divide 839 by 91, we get 9 and a remainder of 20.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 20 after subtracting 819 from 839.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 91

Let's proceed to step 5:
If we divide 209 by 91, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 992.0
Deduct 182 from 209 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 91

Advancing to step 6:
When dividing 273 by 91, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 9923.0
If we subtract 273 from 273, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 91 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9923.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 91 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9923.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9923.0, and the remainder is 0.0.
