84590859 divided by 238 
The aim is to understand the frequency of 238 in 84590859.

Going ahead to step 1:
238 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 238

Step 2:
If we divide 84 by 238, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 238

On to step 3:
238 goes into 845 3 times with a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 714 from 845 and we're left with 131.
Include the next digit (9) from the dividend after 131, then repeat: 1319 / 238

Step 4:
The number 238 fits into 1319 5 times, leaving a remainder of 129.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 1190 away from 1319, we end up with 129.
Grab the next digit (0) from the dividend, add it to 129, then carry on: 1290 / 238

Let's proceed to step 5:
The number 238 fits into 1290 5 times, leaving a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Deduct 1190 from 1290 and we're left with 100.
Take the next digit (8) from the dividend and append it to 100, then repeat: 1008 / 238

Going ahead to step 6:
238 goes into 1008 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 3554.0
If we subtract 952 from 1008, we get 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 238

Moving on to step 7:
238 goes into 565 2 times with a remainder of 89.
Record the quotient 2 as the next digit in the result. 
Result so far: 35542.0
The remainder is 89 after subtracting 476 from 565.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 238

Step 8:
238 can be fit into 899 3 times, resulting in a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 355423.0
If we subtract 714 from 899, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 9:
If we divide 1850 by 238, we get 7 and a remainder of 184.
Use 7 as the next digit of our solution. 
Result so far: 355423.7
Subtracting 1666 from 1850 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 10:
When dividing 1840 by 238, we get 7 with a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 355423.77
If we subtract 1666 from 1840, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The quotient of the division is 355423.77, and the remainder is 0.174.
