Let's divide 71539990 by 610
The aim is to understand the frequency of 610 in 71539990.

Moving on to step 1:
610 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 610

On to step 2:
610 goes into 71 0 times with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 610

Step 3:
If we divide 715 by 610, we get 1 and a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 105 after subtracting 610 from 715.
Take the next digit (3) from the dividend and append it to 105, then repeat: 1053 / 610

On to step 4:
If we divide 1053 by 610, we get 1 and a remainder of 443.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 610 from 1053 and we're left with 443.
Grab the next digit (9) from the dividend, add it to 443, then carry on: 4439 / 610

Moving on to step 5:
610 can be fit into 4439 7 times, resulting in a remainder of 169.
The next digit of our result is 7. 
Result so far: 117.0
If we subtract 4270 from 4439, we get 169.
Include the next digit (9) from the dividend after 169, then repeat: 1699 / 610

Going ahead to step 6:
610 can be fit into 1699 2 times, resulting in a remainder of 479.
The number 2 becomes the next digit in our result. 
Result so far: 1172.0
If we subtract 1220 from 1699, we get 479.
Take the next digit (9) from the dividend and append it to 479, then repeat: 4799 / 610

Step 7:
610 goes into 4799 7 times with a remainder of 529.
Use 7 as the next digit of our solution. 
Result so far: 11727.0
The remainder is 529 after subtracting 4270 from 4799.
Grab the next digit (0) from the dividend, add it to 529, then carry on: 5290 / 610

Let's proceed to step 8:
610 can be fit into 5290 8 times, resulting in a remainder of 410.
Write down 8 as next digit of the result. 
Result so far: 117278.0
Deduct 4880 from 5290 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.

Let's proceed to step 9:
610 goes into 4100 6 times with a remainder of 440.
Put 6 as the next digit of the answer. 
Result so far: 117278.6
The remainder is 440 after subtracting 3660 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 10:
610 goes into 4400 7 times with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 117278.67
If we take 4270 away from 4400, we end up 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.

Step 11:
When dividing 1300 by 610, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 117278.672
The remainder is 80 after subtracting 1220 from 1300.
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 12:
If we divide 800 by 610, we get 1 and a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 117278.6721
The remainder is 190 after subtracting 610 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
When dividing 1900 by 610, we get 3 with a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 117278.67213
If we take 1830 away from 1900, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
If we divide 700 by 610, we get 1 and a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 117278.672131
If we take 610 away from 700, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
When dividing 900 by 610, we get 1 with a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 117278.6721311
Subtract 610 from 900 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The quotient of the division is 117278.6721311, and the remainder is 2.9e-06.
