72117474 ÷ 801 
The aim is to understand the frequency of 801 in 72117474.

Step 1:
The number 801 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 801

Going ahead to step 2:
If we divide 72 by 801, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 801

On to step 3:
When dividing 721 by 801, we get 0 with a remainder of 721.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 721 and we're left with 721.
Include the next digit (1) from the dividend after 721, then repeat: 7211 / 801

Let's proceed to step 4:
When dividing 7211 by 801, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7209 from 7211 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 801

Step 5:
When dividing 27 by 801, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 27 to get 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 801

Advancing to step 6:
The number 801 fits into 274 0 times, leaving a remainder of 274.
Record the quotient 0 as the next digit in the result. 
Result so far: 900.0
If we take 0 away from 274, we end up with 274.
Fetch the next digit (7) from the dividend, attach it to 274 and continue: 2747 / 801

Let's proceed to step 7:
When dividing 2747 by 801, we get 3 with a remainder of 344.
Record the quotient 3 as the next digit in the result. 
Result so far: 9003.0
Subtract 2403 from 2747 to get 344.
Bring next digit (4) of the dividend behind the 344 and repeat the process: 3444 / 801

Moving on to step 8:
801 can be fit into 3444 4 times, resulting in a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 90034.0
If we take 3204 away from 3444, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 9:
801 goes into 2400 2 times with a remainder of 798.
The next digit of our result is 2. 
Result so far: 90034.2
Subtract 1602 from 2400 to get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Let's proceed to step 10:
7980 divided by 801 is 9 with a remainder of 771.
Put 9 as the next digit of the answer. 
Result so far: 90034.29
The remainder is 771 after subtracting 7209 from 7980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Step 11:
When dividing 7710 by 801, we get 9 with a remainder of 501.
The number 9 becomes the next digit in our result. 
Result so far: 90034.299
If we take 7209 away from 7710, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Our division results in 90034.299 with a remaining 0.0501.
