We look at the division of 53203806 by 859 
The aim is to understand the frequency of 859 in 53203806.

Step 1:
859 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 859

Step 2:
If we divide 53 by 859, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 859

Let's proceed to step 3:
859 can be fit into 532 0 times, resulting in a remainder of 532.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 532 to get 532.
Bring next digit (0) of the dividend behind the 532 and repeat the process: 5320 / 859

Step 4:
859 can be fit into 5320 6 times, resulting in a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 5154 from 5320, we get 166.
Append the next digit (3) from the dividend to 166 and continue with: 1663 / 859

On to step 5:
1663 divided by 859 is 1 with a remainder of 804.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Deduct 859 from 1663 and we're left with 804.
Include the next digit (8) from the dividend after 804, then repeat: 8048 / 859

Moving on to step 6:
When dividing 8048 by 859, we get 9 with a remainder of 317.
Record the quotient 9 as the next digit in the result. 
Result so far: 619.0
Subtract 7731 from 8048 to get 317.
Take the next digit (0) from the dividend and append it to 317, then repeat: 3170 / 859

Step 7:
859 can be fit into 3170 3 times, resulting in a remainder of 593.
The next digit of our result is 3. 
Result so far: 6193.0
The remainder is 593 after subtracting 2577 from 3170.
Include the next digit (6) from the dividend after 593, then repeat: 5936 / 859

Let's proceed to step 8:
The number 859 fits into 5936 6 times, leaving a remainder of 782.
Use 6 as the next digit of our solution. 
Result so far: 61936.0
If we subtract 5154 from 5936, we get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Let's proceed to step 9:
859 can be fit into 7820 9 times, resulting in a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 61936.9
Subtracting 7731 from 7820 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 10:
859 can be fit into 890 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 61936.91
If we subtract 859 from 890, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
859 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 61936.91
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 12:
859 can be fit into 3100 3 times, resulting in a remainder of 523.
Record the quotient 3 as the next digit in the result. 
Result so far: 61936.9103
If we take 2577 away from 3100, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 13:
The number 859 fits into 5230 6 times, leaving a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 61936.91036
Deduct 5154 from 5230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
859 can be fit into 760 0 times, resulting in a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 61936.91036
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 15:
859 can be fit into 7600 8 times, resulting in a remainder of 728.
Record the quotient 8 as the next digit in the result. 
Result so far: 61936.9103608
Subtracting 6872 from 7600 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Moving on to step 16:
859 can be fit into 7280 8 times, resulting in a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 61936.91036088
If we subtract 6872 from 7280, we 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.

Our division results in 61936.91036088 with a remaining 4.08e-07.
