56606571 divided by 850 
The aim is to understand the frequency of 850 in 56606571.

Going ahead to step 1:
When dividing 5 by 850, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 850

Moving on to step 2:
850 goes into 56 0 times with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 850

Moving on to step 3:
566 divided by 850 is 0 with a remainder of 566.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 566 and we're left with 566.
Fetch the next digit (0) from the dividend, attach it to 566 and continue: 5660 / 850

Going ahead to step 4:
When dividing 5660 by 850, we get 6 with a remainder of 560.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 5100 away from 5660, we end up with 560.
Take the next digit (6) from the dividend and append it to 560, then repeat: 5606 / 850

Advancing to step 5:
When dividing 5606 by 850, we get 6 with a remainder of 506.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 5100 away from 5606, we end up with 506.
Include the next digit (5) from the dividend after 506, then repeat: 5065 / 850

Step 6:
850 can be fit into 5065 5 times, resulting in a remainder of 815.
Use 5 as the next digit of our solution. 
Result so far: 665.0
Deduct 4250 from 5065 and we're left with 815.
Bring next digit (7) of the dividend behind the 815 and repeat the process: 8157 / 850

Going ahead to step 7:
When dividing 8157 by 850, we get 9 with a remainder of 507.
The number 9 becomes the next digit in our result. 
Result so far: 6659.0
The remainder is 507 after subtracting 7650 from 8157.
Include the next digit (1) from the dividend after 507, then repeat: 5071 / 850

Moving on to step 8:
850 goes into 5071 5 times with a remainder of 821.
The number 5 becomes the next digit in our result. 
Result so far: 66595.0
If we subtract 4250 from 5071, we get 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Let's proceed to step 9:
850 goes into 8210 9 times with a remainder of 560.
Write down 9 as next digit of the result. 
Result so far: 66595.9
If we take 7650 away from 8210, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
If we divide 5600 by 850, we get 6 and a remainder of 500.
The next digit of our result is 6. 
Result so far: 66595.96
If we subtract 5100 from 5600, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
If we divide 5000 by 850, we get 5 and a remainder of 750.
Write down 5 as next digit of the result. 
Result so far: 66595.965
Deduct 4250 from 5000 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 12:
When dividing 7500 by 850, we get 8 with a remainder of 700.
Write down 8 as next digit of the result. 
Result so far: 66595.9658
Subtract 6800 from 7500 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 13:
850 goes into 7000 8 times with a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 66595.96588
Deduct 6800 from 7000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 66595.96588 with a remainder of 0.0002.
