We're dividing 43276891 by 801 
The aim is to understand the frequency of 801 in 43276891.

Moving on to step 1:
If we divide 4 by 801, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 801

Let's proceed to step 2:
801 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 801

Step 3:
801 goes into 432 0 times with a remainder of 432.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 432 leaves us with 432.
Fetch the next digit (7) from the dividend, attach it to 432 and continue: 4327 / 801

Moving on to step 4:
If we divide 4327 by 801, we get 5 and a remainder of 322.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4005 from 4327, we get 322.
Fetch the next digit (6) from the dividend, attach it to 322 and continue: 3226 / 801

Going ahead to step 5:
801 goes into 3226 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
The remainder is 22 after subtracting 3204 from 3226.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 801

Moving on to step 6:
801 goes into 228 0 times with a remainder of 228.
Write down 0 as next digit of the result. 
Result so far: 540.0
If we take 0 away from 228, we end up with 228.
Take the next digit (9) from the dividend and append it to 228, then repeat: 2289 / 801

Step 7:
2289 divided by 801 is 2 with a remainder of 687.
Use 2 as the next digit of our solution. 
Result so far: 5402.0
Subtract 1602 from 2289 to get 687.
Fetch the next digit (1) from the dividend, attach it to 687 and continue: 6871 / 801

Advancing to step 8:
The number 801 fits into 6871 8 times, leaving a remainder of 463.
Record the quotient 8 as the next digit in the result. 
Result so far: 54028.0
Subtract 6408 from 6871 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Moving on to step 9:
801 goes into 4630 5 times with a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 54028.5
If we subtract 4005 from 4630, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 10:
If we divide 6250 by 801, we get 7 and a remainder of 643.
Record the quotient 7 as the next digit in the result. 
Result so far: 54028.57
The remainder is 643 after subtracting 5607 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 11:
When dividing 6430 by 801, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 54028.578
If we take 6408 away from 6430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
The number 801 fits into 220 0 times, leaving a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 54028.578
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
The number 801 fits into 2200 2 times, leaving a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 54028.57802
If we take 1602 away from 2200, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 14:
5980 divided by 801 is 7 with a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 54028.578027
If we subtract 5607 from 5980, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 15:
The number 801 fits into 3730 4 times, leaving a remainder of 526.
The next digit of our result is 4. 
Result so far: 54028.5780274
The remainder is 526 after subtracting 3204 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 16:
When dividing 5260 by 801, we get 6 with a remainder of 454.
Record the quotient 6 as the next digit in the result. 
Result so far: 54028.57802746
Subtracting 4806 from 5260 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

The quotient of the division is 54028.57802746, and the remainder is 4.54e-07.
