The aim is to understand the frequency of 985 in 35805590.

Going ahead to step 1:
If we divide 3 by 985, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 985

On to step 2:
When dividing 35 by 985, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 985

Advancing to step 3:
985 goes into 358 0 times with a remainder of 358.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 358 to get 358.
Append the next digit (0) from the dividend to 358 and continue with: 3580 / 985

Moving on to step 4:
If we divide 3580 by 985, we get 3 and a remainder of 625.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2955 from 3580, we get 625.
Fetch the next digit (5) from the dividend, attach it to 625 and continue: 6255 / 985

Let's proceed to step 5:
6255 divided by 985 is 6 with a remainder of 345.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 5910 from 6255 to get 345.
Grab the next digit (5) from the dividend, add it to 345, then carry on: 3455 / 985

Advancing to step 6:
When dividing 3455 by 985, we get 3 with a remainder of 500.
Write down 3 as next digit of the result. 
Result so far: 363.0
If we subtract 2955 from 3455, we get 500.
Grab the next digit (9) from the dividend, add it to 500, then carry on: 5009 / 985

Moving on to step 7:
If we divide 5009 by 985, we get 5 and a remainder of 84.
Record the quotient 5 as the next digit in the result. 
Result so far: 3635.0
Subtracting 4925 from 5009 leaves us with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 985

Let's proceed to step 8:
840 divided by 985 is 0 with a remainder of 840.
The number 0 becomes the next digit in our result. 
Result so far: 36350.0
The remainder is 840 after subtracting 0 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 9:
If we divide 8400 by 985, we get 8 and a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 36350.8
Subtracting 7880 from 8400 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
985 can be fit into 5200 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 36350.85
Deduct 4925 from 5200 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
2750 divided by 985 is 2 with a remainder of 780.
The number 2 becomes the next digit in our result. 
Result so far: 36350.852
The remainder is 780 after subtracting 1970 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 12:
The number 985 fits into 7800 7 times, leaving a remainder of 905.
Use 7 as the next digit of our solution. 
Result so far: 36350.8527
If we subtract 6895 from 7800, we get 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Moving on to step 13:
985 can be fit into 9050 9 times, resulting in a remainder of 185.
Put 9 as the next digit of the answer. 
Result so far: 36350.85279
The remainder is 185 after subtracting 8865 from 9050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 14:
985 goes into 1850 1 times with a remainder of 865.
The next digit of our result is 1. 
Result so far: 36350.852791
If we subtract 985 from 1850, we get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

On to step 15:
985 can be fit into 8650 8 times, resulting in a remainder of 770.
Write down 8 as next digit of the result. 
Result so far: 36350.8527918
If we subtract 7880 from 8650, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 16:
7700 divided by 985 is 7 with a remainder of 805.
Write down 7 as next digit of the result. 
Result so far: 36350.85279187
If we subtract 6895 from 7700, we get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Our division results in 36350.85279187 with a remaining 8.05e-07.
