We're dividing 84363321 by 253 
The aim is to understand the frequency of 253 in 84363321.

Moving on to step 1:
253 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 253

Step 2:
253 can be fit into 84 0 times, resulting in a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 253

On to step 3:
253 goes into 843 3 times with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 759 from 843, we get 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 253

Step 4:
When dividing 846 by 253, we get 3 with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 759 from 846 leaves us with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 253

Advancing to step 5:
253 goes into 873 3 times with a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 333.0
Deduct 759 from 873 and we're left with 114.
Bring next digit (3) of the dividend behind the 114 and repeat the process: 1143 / 253

Going ahead to step 6:
253 goes into 1143 4 times with a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 3334.0
Subtract 1012 from 1143 to get 131.
Fetch the next digit (2) from the dividend, attach it to 131 and continue: 1312 / 253

Advancing to step 7:
If we divide 1312 by 253, we get 5 and a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 33345.0
Deduct 1265 from 1312 and we're left with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 253

Let's proceed to step 8:
471 divided by 253 is 1 with a remainder of 218.
Put 1 as the next digit of the answer. 
Result so far: 333451.0
If we subtract 253 from 471, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 9:
When dividing 2180 by 253, we get 8 with a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 333451.8
Subtract 2024 from 2180 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
When dividing 1560 by 253, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 333451.86
Subtract 1518 from 1560 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
When dividing 420 by 253, we get 1 with a remainder of 167.
The next digit of our result is 1. 
Result so far: 333451.861
If we subtract 253 from 420, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 12:
If we divide 1670 by 253, we get 6 and a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 333451.8616
Subtracting 1518 from 1670 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 13:
253 goes into 1520 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 333451.86166
Subtract 1518 from 1520 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 333451.86166, with a leftover of 2e-06.
