We look at the division of 85740594 by 849 
The aim is to understand the frequency of 849 in 85740594.

Let's proceed to step 1:
When dividing 8 by 849, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 849

Advancing to step 2:
849 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (7) from the dividend and append it to 85, then repeat: 857 / 849

Let's proceed to step 3:
849 can be fit into 857 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 849 from 857, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 849

Going ahead to step 4:
849 goes into 84 0 times with a remainder of 84.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 84 to get 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 849

On to step 5:
If we divide 840 by 849, we get 0 and a remainder of 840.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 840 leaves us with 840.
Append the next digit (5) from the dividend to 840 and continue with: 8405 / 849

Going ahead to step 6:
849 goes into 8405 9 times with a remainder of 764.
Record the quotient 9 as the next digit in the result. 
Result so far: 1009.0
Subtract 7641 from 8405 to get 764.
Grab the next digit (9) from the dividend, add it to 764, then carry on: 7649 / 849

Let's proceed to step 7:
849 goes into 7649 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 10099.0
Subtracting 7641 from 7649 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 849

On to step 8:
84 divided by 849 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 100990.0
Subtracting 0 from 84 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
849 goes into 840 0 times with a remainder of 840.
The next digit of our result is 0. 
Result so far: 100990.0
If we subtract 0 from 840, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 10:
8400 divided by 849 is 9 with a remainder of 759.
The number 9 becomes the next digit in our result. 
Result so far: 100990.09
If we subtract 7641 from 8400, we get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Going ahead to step 11:
If we divide 7590 by 849, we get 8 and a remainder of 798.
Put 8 as the next digit of the answer. 
Result so far: 100990.098
Subtracting 6792 from 7590 leaves us with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

On to step 12:
849 can be fit into 7980 9 times, resulting in a remainder of 339.
Write down 9 as next digit of the result. 
Result so far: 100990.0989
Deduct 7641 from 7980 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 13:
If we divide 3390 by 849, we get 3 and a remainder of 843.
Record the quotient 3 as the next digit in the result. 
Result so far: 100990.09893
If we subtract 2547 from 3390, we get 843.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8430, and continue the process.

Advancing to step 14:
8430 divided by 849 is 9 with a remainder of 789.
The next digit of our result is 9. 
Result so far: 100990.098939
If we subtract 7641 from 8430, we get 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

On to step 15:
7890 divided by 849 is 9 with a remainder of 249.
Put 9 as the next digit of the answer. 
Result so far: 100990.0989399
The remainder is 249 after subtracting 7641 from 7890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

The final outcome is 100990.0989399, with a leftover of 2.49e-06.
