We divide 290389 by 91
We want to figure out the number of times 290389 can be divided by 91.

On to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 91

Step 2:
29 divided by 91 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 91

Going ahead to step 3:
290 divided by 91 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 273 from 290, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 91

Advancing to step 4:
If we divide 173 by 91, we get 1 and a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 91 from 173, we get 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 91

Moving on to step 5:
The number 91 fits into 828 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 319.0
Subtract 819 from 828 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 91

On to step 6:
99 divided by 91 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 3191.0
Subtract 91 from 99 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
91 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 3191.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
The number 91 fits into 800 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 3191.08
If we subtract 728 from 800, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
The number 91 fits into 720 7 times, leaving a remainder of 83.
The next digit of our result is 7. 
Result so far: 3191.087
Deduct 637 from 720 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
When dividing 830 by 91, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 3191.0879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
91 goes into 110 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 3191.08791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
190 divided by 91 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3191.087912
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
When dividing 80 by 91, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 3191.087912
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 91 fits into 800 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 3191.08791208
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 3191.08791208 and a remainder of 7.2e-08.
