We're dividing 67209391 by 610 
The aim is to understand the frequency of 610 in 67209391.

On to step 1:
610 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 610

Going ahead to step 2:
When dividing 67 by 610, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 610

Advancing to step 3:
610 can be fit into 672 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 610 from 672 leaves us with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 610

Advancing to step 4:
610 goes into 620 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 610 from 620, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 610

Going ahead to step 5:
When dividing 109 by 610, we get 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtracting 0 from 109 leaves us with 109.
Fetch the next digit (3) from the dividend, attach it to 109 and continue: 1093 / 610

Let's proceed to step 6:
If we divide 1093 by 610, we get 1 and a remainder of 483.
The number 1 becomes the next digit in our result. 
Result so far: 1101.0
If we subtract 610 from 1093, we get 483.
Append the next digit (9) from the dividend to 483 and continue with: 4839 / 610

Going ahead to step 7:
If we divide 4839 by 610, we get 7 and a remainder of 569.
Record the quotient 7 as the next digit in the result. 
Result so far: 11017.0
Subtract 4270 from 4839 to get 569.
Append the next digit (1) from the dividend to 569 and continue with: 5691 / 610

Step 8:
5691 divided by 610 is 9 with a remainder of 201.
The next digit of our result is 9. 
Result so far: 110179.0
If we take 5490 away from 5691, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 9:
When dividing 2010 by 610, we get 3 with a remainder of 180.
Write down 3 as next digit of the result. 
Result so far: 110179.3
The remainder is 180 after subtracting 1830 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
If we divide 1800 by 610, we get 2 and a remainder of 580.
Record the quotient 2 as the next digit in the result. 
Result so far: 110179.32
Subtracting 1220 from 1800 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
If we divide 5800 by 610, we get 9 and a remainder of 310.
Write down 9 as next digit of the result. 
Result so far: 110179.329
Subtract 5490 from 5800 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
610 goes into 3100 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 110179.3295
Subtracting 3050 from 3100 leaves us 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.

Step 13:
The number 610 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 110179.3295
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
If we divide 5000 by 610, we get 8 and a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 110179.329508
If we take 4880 away from 5000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
610 goes into 1200 1 times with a remainder of 590.
Write down 1 as next digit of the result. 
Result so far: 110179.3295081
If we subtract 610 from 1200, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 16:
610 goes into 5900 9 times with a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 110179.32950819
Deduct 5490 from 5900 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final outcome is 110179.32950819, with a leftover of 4.1e-07.
