We're dividing 84467145 by 821 
The aim is to understand the frequency of 821 in 84467145.

Step 1:
If we divide 8 by 821, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 821

Advancing to step 2:
The number 821 fits into 84 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 821

Advancing to step 3:
844 divided by 821 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 821 from 844 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 821

Let's proceed to step 4:
The number 821 fits into 236 0 times, leaving a remainder of 236.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 236 and we're left with 236.
Bring next digit (7) of the dividend behind the 236 and repeat the process: 2367 / 821

Going ahead to step 5:
The number 821 fits into 2367 2 times, leaving a remainder of 725.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 1642 from 2367 to get 725.
Append the next digit (1) from the dividend to 725 and continue with: 7251 / 821

Going ahead to step 6:
7251 divided by 821 is 8 with a remainder of 683.
The next digit of our result is 8. 
Result so far: 1028.0
If we take 6568 away from 7251, we end up with 683.
Take the next digit (4) from the dividend and append it to 683, then repeat: 6834 / 821

Step 7:
821 can be fit into 6834 8 times, resulting in a remainder of 266.
Put 8 as the next digit of the answer. 
Result so far: 10288.0
If we subtract 6568 from 6834, we get 266.
Append the next digit (5) from the dividend to 266 and continue with: 2665 / 821

Advancing to step 8:
The number 821 fits into 2665 3 times, leaving a remainder of 202.
Record the quotient 3 as the next digit in the result. 
Result so far: 102883.0
If we subtract 2463 from 2665, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 9:
821 goes into 2020 2 times with a remainder of 378.
The next digit of our result is 2. 
Result so far: 102883.2
Subtracting 1642 from 2020 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 10:
If we divide 3780 by 821, we get 4 and a remainder of 496.
The next digit of our result is 4. 
Result so far: 102883.24
The remainder is 496 after subtracting 3284 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 11:
4960 divided by 821 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 102883.246
Deduct 4926 from 4960 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
If we divide 340 by 821, we get 0 and a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 102883.246
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 13:
3400 divided by 821 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 102883.24604
If we subtract 3284 from 3400, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 14:
821 goes into 1160 1 times with a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 102883.246041
Deduct 821 from 1160 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 15:
3390 divided by 821 is 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 102883.2460414
Subtracting 3284 from 3390 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 16:
821 can be fit into 1060 1 times, resulting in a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 102883.24604141
Subtracting 821 from 1060 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The quotient of the division is 102883.24604141, and the remainder is 2.39e-07.
