80721848 divided by 290 
The aim is to understand the frequency of 290 in 80721848.

Step 1:
The number 290 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 290

Moving on to step 2:
290 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 290

Advancing to step 3:
If we divide 807 by 290, we get 2 and a remainder of 227.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 580 from 807 leaves us with 227.
Append the next digit (2) from the dividend to 227 and continue with: 2272 / 290

Advancing to step 4:
The number 290 fits into 2272 7 times, leaving a remainder of 242.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 2030 from 2272 to get 242.
Fetch the next digit (1) from the dividend, attach it to 242 and continue: 2421 / 290

Advancing to step 5:
The number 290 fits into 2421 8 times, leaving a remainder of 101.
The next digit of our result is 8. 
Result so far: 278.0
If we subtract 2320 from 2421, we get 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 290

Going ahead to step 6:
290 can be fit into 1018 3 times, resulting in a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 2783.0
Subtract 870 from 1018 to get 148.
Append the next digit (4) from the dividend to 148 and continue with: 1484 / 290

Moving on to step 7:
When dividing 1484 by 290, we get 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 27835.0
Deduct 1450 from 1484 and we're left with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 290

Step 8:
290 goes into 348 1 times with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 278351.0
If we take 290 away from 348, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
290 can be fit into 580 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 278351.2
Subtracting 580 from 580 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
290 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 278351.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 290, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 278351.2
Deduct 0 from 0 and we're left with 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 278351.2, and the remainder is 0.0.
