84532874 ÷ 810 
The aim is to understand the frequency of 810 in 84532874.

Step 1:
When dividing 8 by 810, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 810

Moving on to step 2:
810 goes into 84 0 times with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 810

Moving on to step 3:
810 can be fit into 845 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 810 from 845, we get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 810

On to step 4:
810 goes into 353 0 times with a remainder of 353.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 353 and we're left with 353.
Bring next digit (2) of the dividend behind the 353 and repeat the process: 3532 / 810

Advancing to step 5:
The number 810 fits into 3532 4 times, leaving a remainder of 292.
The next digit of our result is 4. 
Result so far: 104.0
The remainder is 292 after subtracting 3240 from 3532.
Fetch the next digit (8) from the dividend, attach it to 292 and continue: 2928 / 810

On to step 6:
The number 810 fits into 2928 3 times, leaving a remainder of 498.
Put 3 as the next digit of the answer. 
Result so far: 1043.0
Subtract 2430 from 2928 to get 498.
Bring next digit (7) of the dividend behind the 498 and repeat the process: 4987 / 810

Advancing to step 7:
810 goes into 4987 6 times with a remainder of 127.
The number 6 becomes the next digit in our result. 
Result so far: 10436.0
Subtracting 4860 from 4987 leaves us with 127.
Fetch the next digit (4) from the dividend, attach it to 127 and continue: 1274 / 810

Moving on to step 8:
When dividing 1274 by 810, we get 1 with a remainder of 464.
Write down 1 as next digit of the result. 
Result so far: 104361.0
Subtract 810 from 1274 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 9:
When dividing 4640 by 810, we get 5 with a remainder of 590.
Put 5 as the next digit of the answer. 
Result so far: 104361.5
Subtract 4050 from 4640 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 10:
5900 divided by 810 is 7 with a remainder of 230.
Record the quotient 7 as the next digit in the result. 
Result so far: 104361.57
Subtracting 5670 from 5900 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 11:
2300 divided by 810 is 2 with a remainder of 680.
Write down 2 as next digit of the result. 
Result so far: 104361.572
Deduct 1620 from 2300 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 12:
810 goes into 6800 8 times with a remainder of 320.
The number 8 becomes the next digit in our result. 
Result so far: 104361.5728
Deduct 6480 from 6800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
If we divide 3200 by 810, we get 3 and a remainder of 770.
The next digit of our result is 3. 
Result so far: 104361.57283
If we take 2430 away from 3200, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 14:
810 goes into 7700 9 times with a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 104361.572839
Deduct 7290 from 7700 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 15:
When dividing 4100 by 810, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 104361.5728395
Subtracting 4050 from 4100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
500 divided by 810 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 104361.5728395
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 104361.5728395 and a remainder of 5e-07.
