44119435 ÷ 210 
The aim is to understand the frequency of 210 in 44119435.

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
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 210

On to step 2:
The number 210 fits into 44 0 times, leaving a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 210

Step 3:
210 goes into 441 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 420 away from 441, we end up with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 210

Advancing to step 4:
211 divided by 210 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 210 from 211 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 210

Let's proceed to step 5:
19 divided by 210 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 210

Advancing to step 6:
If we divide 194 by 210, we get 0 and a remainder of 194.
Write down 0 as next digit of the result. 
Result so far: 2100.0
Deduct 0 from 194 and we're left with 194.
Take the next digit (3) from the dividend and append it to 194, then repeat: 1943 / 210

Let's proceed to step 7:
The number 210 fits into 1943 9 times, leaving a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 21009.0
Subtracting 1890 from 1943 leaves us with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 210

Going ahead to step 8:
The number 210 fits into 535 2 times, leaving a remainder of 115.
Use 2 as the next digit of our solution. 
Result so far: 210092.0
The remainder is 115 after subtracting 420 from 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
210 can be fit into 1150 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 210092.5
Deduct 1050 from 1150 and we're left 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.

Step 10:
1000 divided by 210 is 4 with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 210092.54
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
1600 divided by 210 is 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 210092.547
Deduct 1470 from 1600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
The number 210 fits into 1300 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 210092.5476
Subtracting 1260 from 1300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
When dividing 400 by 210, we get 1 with a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 210092.54761
Deduct 210 from 400 and we're left 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.

Advancing to step 14:
When dividing 1900 by 210, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 210092.547619
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.

Advancing to step 15:
The number 210 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 210092.547619
Subtract 0 from 100 to get 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 16:
210 goes into 1000 4 times with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 210092.54761904
If we take 840 away from 1000, we end up 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.

The final result is 210092.54761904 with a remainder of 1.6e-07.
