We're dividing 44159845 by 210 
The aim is to understand the frequency of 210 in 44159845.

Let's proceed to step 1:
When dividing 4 by 210, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 210

Let's proceed to step 2:
210 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 210

Moving on to step 3:
When dividing 441 by 210, we get 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 420 from 441 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 210

Step 4:
If we divide 215 by 210, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 210 from 215 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 210

Moving on to step 5:
The number 210 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we subtract 0 from 59, we get 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 210

On to step 6:
The number 210 fits into 598 2 times, leaving a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 2102.0
Subtracting 420 from 598 leaves us with 178.
Take the next digit (4) from the dividend and append it to 178, then repeat: 1784 / 210

Step 7:
The number 210 fits into 1784 8 times, leaving a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 21028.0
If we take 1680 away from 1784, we end up with 104.
Take the next digit (5) from the dividend and append it to 104, then repeat: 1045 / 210

Advancing to step 8:
210 goes into 1045 4 times with a remainder of 205.
The number 4 becomes the next digit in our result. 
Result so far: 210284.0
If we take 840 away from 1045, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
210 goes into 2050 9 times with a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 210284.9
Subtracting 1890 from 2050 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
210 goes into 1600 7 times with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 210284.97
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
When dividing 1300 by 210, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 210284.976
If we subtract 1260 from 1300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
If we divide 400 by 210, we get 1 and a remainder of 190.
The next digit of our result is 1. 
Result so far: 210284.9761
Subtracting 210 from 400 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 13:
When dividing 1900 by 210, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 210284.97619
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
100 divided by 210 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 210284.97619
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
210 can be fit into 1000 4 times, resulting in a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 210284.9761904
Deduct 840 from 1000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 16:
The number 210 fits into 1600 7 times, leaving a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 210284.97619047
Subtract 1470 from 1600 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final result is 210284.97619047 with a remainder of 1.3e-07.
