Let's divide 80085835 by 407
The aim is to understand the frequency of 407 in 80085835.

Step 1:
The number 407 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 407

Moving on to step 2:
407 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 407

Let's proceed to step 3:
When dividing 800 by 407, we get 1 with a remainder of 393.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 407 from 800, we get 393.
Grab the next digit (8) from the dividend, add it to 393, then carry on: 3938 / 407

Step 4:
The number 407 fits into 3938 9 times, leaving a remainder of 275.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 3663 from 3938 to get 275.
Bring next digit (5) of the dividend behind the 275 and repeat the process: 2755 / 407

Step 5:
2755 divided by 407 is 6 with a remainder of 313.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Deduct 2442 from 2755 and we're left with 313.
Grab the next digit (8) from the dividend, add it to 313, then carry on: 3138 / 407

Going ahead to step 6:
3138 divided by 407 is 7 with a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 1967.0
Subtract 2849 from 3138 to get 289.
Bring next digit (3) of the dividend behind the 289 and repeat the process: 2893 / 407

Moving on to step 7:
When dividing 2893 by 407, we get 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 19677.0
If we subtract 2849 from 2893, we get 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 407

On to step 8:
445 divided by 407 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 196771.0
Subtract 407 from 445 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
When dividing 380 by 407, we get 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 196771.0
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 10:
407 goes into 3800 9 times with a remainder of 137.
Record the quotient 9 as the next digit in the result. 
Result so far: 196771.09
If we subtract 3663 from 3800, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 11:
The number 407 fits into 1370 3 times, leaving a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 196771.093
If we subtract 1221 from 1370, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 12:
If we divide 1490 by 407, we get 3 and a remainder of 269.
Write down 3 as next digit of the result. 
Result so far: 196771.0933
Subtract 1221 from 1490 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final result is 196771.0933 with a remainder of 0.00269.
