We're dividing 84505623 by 610 
The aim is to understand the frequency of 610 in 84505623.

On to step 1:
8 divided by 610 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 610

Going ahead to step 2:
84 divided by 610 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 610

Step 3:
610 goes into 845 1 times with a remainder of 235.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 610 from 845, we get 235.
Append the next digit (0) from the dividend to 235 and continue with: 2350 / 610

On to step 4:
610 goes into 2350 3 times with a remainder of 520.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1830 from 2350 and we're left with 520.
Grab the next digit (5) from the dividend, add it to 520, then carry on: 5205 / 610

On to step 5:
When dividing 5205 by 610, we get 8 with a remainder of 325.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 4880 from 5205 to get 325.
Take the next digit (6) from the dividend and append it to 325, then repeat: 3256 / 610

On to step 6:
3256 divided by 610 is 5 with a remainder of 206.
Write down 5 as next digit of the result. 
Result so far: 1385.0
Deduct 3050 from 3256 and we're left with 206.
Fetch the next digit (2) from the dividend, attach it to 206 and continue: 2062 / 610

Advancing to step 7:
2062 divided by 610 is 3 with a remainder of 232.
Use 3 as the next digit of our solution. 
Result so far: 13853.0
Subtracting 1830 from 2062 leaves us with 232.
Bring next digit (3) of the dividend behind the 232 and repeat the process: 2323 / 610

Advancing to step 8:
When dividing 2323 by 610, we get 3 with a remainder of 493.
Put 3 as the next digit of the answer. 
Result so far: 138533.0
Subtract 1830 from 2323 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 9:
The number 610 fits into 4930 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 138533.8
Deduct 4880 from 4930 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.

Step 10:
500 divided by 610 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 138533.8
If we take 0 away from 500, we end up 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.

Advancing to step 11:
610 goes into 5000 8 times with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 138533.808
If we subtract 4880 from 5000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
If we divide 1200 by 610, we get 1 and a remainder of 590.
Record the quotient 1 as the next digit in the result. 
Result so far: 138533.8081
The remainder is 590 after subtracting 610 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 13:
The number 610 fits into 5900 9 times, leaving a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 138533.80819
Subtract 5490 from 5900 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 14:
610 goes into 4100 6 times with a remainder of 440.
Use 6 as the next digit of our solution. 
Result so far: 138533.808196
If we take 3660 away from 4100, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
If we divide 4400 by 610, we get 7 and a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 138533.8081967
Subtracting 4270 from 4400 leaves us 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.

Let's proceed to step 16:
The number 610 fits into 1300 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 138533.80819672
Subtracting 1220 from 1300 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 138533.80819672, with a leftover of 8e-08.
