7812085 ÷ 801 
The aim is to understand the frequency of 801 in 7812085.

Step 1:
801 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 801

Going ahead to step 2:
When dividing 78 by 801, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 801

Let's proceed to step 3:
The number 801 fits into 781 0 times, leaving a remainder of 781.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 781, we get 781.
Append the next digit (2) from the dividend to 781 and continue with: 7812 / 801

On to step 4:
801 goes into 7812 9 times with a remainder of 603.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 603 after subtracting 7209 from 7812.
Grab the next digit (0) from the dividend, add it to 603, then carry on: 6030 / 801

On to step 5:
801 can be fit into 6030 7 times, resulting in a remainder of 423.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 423 after subtracting 5607 from 6030.
Bring next digit (8) of the dividend behind the 423 and repeat the process: 4238 / 801

Going ahead to step 6:
801 goes into 4238 5 times with a remainder of 233.
The next digit of our result is 5. 
Result so far: 975.0
Deduct 4005 from 4238 and we're left with 233.
Grab the next digit (5) from the dividend, add it to 233, then carry on: 2335 / 801

Moving on to step 7:
801 can be fit into 2335 2 times, resulting in a remainder of 733.
The next digit of our result is 2. 
Result so far: 9752.0
Subtracting 1602 from 2335 leaves us with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Advancing to step 8:
The number 801 fits into 7330 9 times, leaving a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 9752.9
Subtract 7209 from 7330 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
The number 801 fits into 1210 1 times, leaving a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 9752.91
Deduct 801 from 1210 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 10:
4090 divided by 801 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 9752.915
If we subtract 4005 from 4090, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
850 divided by 801 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 9752.9151
If we subtract 801 from 850, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
When dividing 490 by 801, we get 0 with a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 9752.9151
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
801 goes into 4900 6 times with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 9752.915106
If we subtract 4806 from 4900, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 14:
940 divided by 801 is 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 9752.9151061
The remainder is 139 after subtracting 801 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 15:
801 can be fit into 1390 1 times, resulting in a remainder of 589.
Write down 1 as next digit of the result. 
Result so far: 9752.91510611
The remainder is 589 after subtracting 801 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Our division results in 9752.91510611 with a remaining 5.89e-07.
