We're dividing 59898005 by 210 
The aim is to understand the frequency of 210 in 59898005.

Let's proceed to step 1:
5 divided by 210 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 210

On to step 2:
210 goes into 59 0 times with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 210

Advancing to step 3:
210 can be fit into 598 2 times, resulting in a remainder of 178.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 420 from 598 to get 178.
Bring next digit (9) of the dividend behind the 178 and repeat the process: 1789 / 210

Step 4:
When dividing 1789 by 210, we get 8 with a remainder of 109.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 1680 away from 1789, we end up with 109.
Include the next digit (8) from the dividend after 109, then repeat: 1098 / 210

Going ahead to step 5:
210 goes into 1098 5 times with a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
If we subtract 1050 from 1098, we get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 210

Advancing to step 6:
480 divided by 210 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 2852.0
The remainder is 60 after subtracting 420 from 480.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 210

Going ahead to step 7:
The number 210 fits into 600 2 times, leaving a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 28522.0
Subtracting 420 from 600 leaves us with 180.
Take the next digit (5) from the dividend and append it to 180, then repeat: 1805 / 210

Moving on to step 8:
1805 divided by 210 is 8 with a remainder of 125.
Put 8 as the next digit of the answer. 
Result so far: 285228.0
If we take 1680 away from 1805, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
If we divide 1250 by 210, we get 5 and a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 285228.5
Deduct 1050 from 1250 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
When dividing 2000 by 210, we get 9 with a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 285228.59
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
1100 divided by 210 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 285228.595
Deduct 1050 from 1100 and we're left 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.

Moving on to step 12:
If we divide 500 by 210, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 285228.5952
Subtract 420 from 500 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
800 divided by 210 is 3 with a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 285228.59523
The remainder is 170 after subtracting 630 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 14:
When dividing 1700 by 210, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 285228.595238
Subtracting 1680 from 1700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
The number 210 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 285228.595238
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
210 can be fit into 2000 9 times, resulting in a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 285228.59523809
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Our division results in 285228.59523809 with a remaining 1.1e-07.
