23800990 divided by 802 
The aim is to understand the frequency of 802 in 23800990.

Advancing to step 1:
802 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 802

Moving on to step 2:
802 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 802

Step 3:
The number 802 fits into 238 0 times, leaving a remainder of 238.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 238 to get 238.
Fetch the next digit (0) from the dividend, attach it to 238 and continue: 2380 / 802

Let's proceed to step 4:
If we divide 2380 by 802, we get 2 and a remainder of 776.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1604 from 2380, we get 776.
Fetch the next digit (0) from the dividend, attach it to 776 and continue: 7760 / 802

Advancing to step 5:
7760 divided by 802 is 9 with a remainder of 542.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 7218 from 7760 and we're left with 542.
Append the next digit (9) from the dividend to 542 and continue with: 5429 / 802

Moving on to step 6:
802 can be fit into 5429 6 times, resulting in a remainder of 617.
Write down 6 as next digit of the result. 
Result so far: 296.0
Subtract 4812 from 5429 to get 617.
Bring next digit (9) of the dividend behind the 617 and repeat the process: 6179 / 802

Step 7:
6179 divided by 802 is 7 with a remainder of 565.
Put 7 as the next digit of the answer. 
Result so far: 2967.0
If we take 5614 away from 6179, we end up with 565.
Bring next digit (0) of the dividend behind the 565 and repeat the process: 5650 / 802

Let's proceed to step 8:
802 can be fit into 5650 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 29677.0
If we take 5614 away from 5650, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
802 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 29677.0
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 10:
802 goes into 3600 4 times with a remainder of 392.
The next digit of our result is 4. 
Result so far: 29677.04
Subtract 3208 from 3600 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 11:
3920 divided by 802 is 4 with a remainder of 712.
Record the quotient 4 as the next digit in the result. 
Result so far: 29677.044
If we subtract 3208 from 3920, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Our division results in 29677.044 with a remaining 0.0712.
