We're dividing 75024070 by 859 
The aim is to understand the frequency of 859 in 75024070.

Step 1:
7 divided by 859 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 859

Step 2:
If we divide 75 by 859, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 859

Moving on to step 3:
If we divide 750 by 859, we get 0 and a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 750, we end up with 750.
Grab the next digit (2) from the dividend, add it to 750, then carry on: 7502 / 859

Going ahead to step 4:
When dividing 7502 by 859, we get 8 with a remainder of 630.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6872 from 7502 leaves us with 630.
Append the next digit (4) from the dividend to 630 and continue with: 6304 / 859

Let's proceed to step 5:
If we divide 6304 by 859, we get 7 and a remainder of 291.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 6013 from 6304, we get 291.
Bring next digit (0) of the dividend behind the 291 and repeat the process: 2910 / 859

Advancing to step 6:
859 can be fit into 2910 3 times, resulting in a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 873.0
Subtract 2577 from 2910 to get 333.
Fetch the next digit (7) from the dividend, attach it to 333 and continue: 3337 / 859

Advancing to step 7:
If we divide 3337 by 859, we get 3 and a remainder of 760.
Write down 3 as next digit of the result. 
Result so far: 8733.0
Subtract 2577 from 3337 to get 760.
Bring next digit (0) of the dividend behind the 760 and repeat the process: 7600 / 859

Advancing to step 8:
When dividing 7600 by 859, we get 8 with a remainder of 728.
Use 8 as the next digit of our solution. 
Result so far: 87338.0
If we subtract 6872 from 7600, we get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 9:
When dividing 7280 by 859, we get 8 with a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 87338.8
Subtract 6872 from 7280 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
If we divide 4080 by 859, we get 4 and a remainder of 644.
Write down 4 as next digit of the result. 
Result so far: 87338.84
Subtracting 3436 from 4080 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 11:
859 can be fit into 6440 7 times, resulting in a remainder of 427.
Put 7 as the next digit of the answer. 
Result so far: 87338.847
If we take 6013 away from 6440, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Step 12:
859 can be fit into 4270 4 times, resulting in a remainder of 834.
Use 4 as the next digit of our solution. 
Result so far: 87338.8474
Subtracting 3436 from 4270 leaves us with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Let's proceed to step 13:
When dividing 8340 by 859, we get 9 with a remainder of 609.
Record the quotient 9 as the next digit in the result. 
Result so far: 87338.84749
Subtracting 7731 from 8340 leaves us with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Advancing to step 14:
The number 859 fits into 6090 7 times, leaving a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 87338.847497
The remainder is 77 after subtracting 6013 from 6090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 15:
If we divide 770 by 859, we get 0 and a remainder of 770.
Use 0 as the next digit of our solution. 
Result so far: 87338.847497
Subtracting 0 from 770 leaves us with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 16:
The number 859 fits into 7700 8 times, leaving a remainder of 828.
The next digit of our result is 8. 
Result so far: 87338.84749708
If we subtract 6872 from 7700, we get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

The final outcome is 87338.84749708, with a leftover of 8.28e-07.
