We're dividing 11505739 by 801 
The aim is to understand the frequency of 801 in 11505739.

Let's proceed to step 1:
801 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 801

Let's proceed to step 2:
801 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 801

Advancing to step 3:
The number 801 fits into 115 0 times, leaving a remainder of 115.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 115 to get 115.
Bring next digit (0) of the dividend behind the 115 and repeat the process: 1150 / 801

On to step 4:
801 can be fit into 1150 1 times, resulting in a remainder of 349.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 801 from 1150 and we're left with 349.
Bring next digit (5) of the dividend behind the 349 and repeat the process: 3495 / 801

Going ahead to step 5:
3495 divided by 801 is 4 with a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 3204 from 3495, we get 291.
Bring next digit (7) of the dividend behind the 291 and repeat the process: 2917 / 801

Moving on to step 6:
If we divide 2917 by 801, we get 3 and a remainder of 514.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
If we subtract 2403 from 2917, we get 514.
Grab the next digit (3) from the dividend, add it to 514, then carry on: 5143 / 801

On to step 7:
The number 801 fits into 5143 6 times, leaving a remainder of 337.
The next digit of our result is 6. 
Result so far: 1436.0
Deduct 4806 from 5143 and we're left with 337.
Take the next digit (9) from the dividend and append it to 337, then repeat: 3379 / 801

Let's proceed to step 8:
801 goes into 3379 4 times with a remainder of 175.
The next digit of our result is 4. 
Result so far: 14364.0
The remainder is 175 after subtracting 3204 from 3379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 9:
1750 divided by 801 is 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 14364.2
If we subtract 1602 from 1750, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 10:
1480 divided by 801 is 1 with a remainder of 679.
The next digit of our result is 1. 
Result so far: 14364.21
The remainder is 679 after subtracting 801 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 11:
The number 801 fits into 6790 8 times, leaving a remainder of 382.
Record the quotient 8 as the next digit in the result. 
Result so far: 14364.218
If we subtract 6408 from 6790, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 12:
If we divide 3820 by 801, we get 4 and a remainder of 616.
Put 4 as the next digit of the answer. 
Result so far: 14364.2184
Subtracting 3204 from 3820 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 13:
801 goes into 6160 7 times with a remainder of 553.
The next digit of our result is 7. 
Result so far: 14364.21847
Subtract 5607 from 6160 to get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 14:
The number 801 fits into 5530 6 times, leaving a remainder of 724.
Use 6 as the next digit of our solution. 
Result so far: 14364.218476
If we subtract 4806 from 5530, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 15:
801 goes into 7240 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 14364.2184769
Subtracting 7209 from 7240 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 16:
The number 801 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 14364.2184769
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 14364.2184769, with a leftover of 3.1e-07.
