We divide 8509419 by 801
The aim is to understand the frequency of 801 in 8509419.

Advancing to step 1:
The number 801 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 801

Moving on to step 2:
85 divided by 801 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 801

Moving on to step 3:
When dividing 850 by 801, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 801 from 850, we get 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 801

Moving on to step 4:
The number 801 fits into 499 0 times, leaving a remainder of 499.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 499, we get 499.
Take the next digit (4) from the dividend and append it to 499, then repeat: 4994 / 801

On to step 5:
When dividing 4994 by 801, we get 6 with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we take 4806 away from 4994, we end up with 188.
Grab the next digit (1) from the dividend, add it to 188, then carry on: 1881 / 801

On to step 6:
The number 801 fits into 1881 2 times, leaving a remainder of 279.
The next digit of our result is 2. 
Result so far: 1062.0
Subtract 1602 from 1881 to get 279.
Append the next digit (9) from the dividend to 279 and continue with: 2799 / 801

On to step 7:
If we divide 2799 by 801, we get 3 and a remainder of 396.
The next digit of our result is 3. 
Result so far: 10623.0
If we subtract 2403 from 2799, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 8:
801 goes into 3960 4 times with a remainder of 756.
The number 4 becomes the next digit in our result. 
Result so far: 10623.4
If we take 3204 away from 3960, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

On to step 9:
If we divide 7560 by 801, we get 9 and a remainder of 351.
Use 9 as the next digit of our solution. 
Result so far: 10623.49
The remainder is 351 after subtracting 7209 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 10:
801 goes into 3510 4 times with a remainder of 306.
Use 4 as the next digit of our solution. 
Result so far: 10623.494
If we take 3204 away from 3510, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
801 can be fit into 3060 3 times, resulting in a remainder of 657.
Write down 3 as next digit of the result. 
Result so far: 10623.4943
Subtract 2403 from 3060 to get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Moving on to step 12:
When dividing 6570 by 801, we get 8 with a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 10623.49438
If we take 6408 away from 6570, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 13:
If we divide 1620 by 801, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 10623.494382
The remainder is 18 after subtracting 1602 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
The number 801 fits into 180 0 times, leaving a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 10623.494382
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
801 can be fit into 1800 2 times, resulting in a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 10623.49438202
Subtracting 1602 from 1800 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

In conclusion, the division gives 10623.49438202 with a balance of 1.98e-07.
