84070089 divided by 258 
The aim is to understand the frequency of 258 in 84070089.

On to step 1:
258 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 258

Step 2:
If we divide 84 by 258, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 258

Step 3:
When dividing 840 by 258, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 774 from 840, we get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 258

Going ahead to step 4:
If we divide 667 by 258, we get 2 and a remainder of 151.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 516 away from 667, we end up with 151.
Append the next digit (0) from the dividend to 151 and continue with: 1510 / 258

On to step 5:
When dividing 1510 by 258, we get 5 with a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 325.0
Subtract 1290 from 1510 to get 220.
Fetch the next digit (0) from the dividend, attach it to 220 and continue: 2200 / 258

Moving on to step 6:
258 can be fit into 2200 8 times, resulting in a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 3258.0
Subtracting 2064 from 2200 leaves us with 136.
Grab the next digit (8) from the dividend, add it to 136, then carry on: 1368 / 258

On to step 7:
When dividing 1368 by 258, we get 5 with a remainder of 78.
Record the quotient 5 as the next digit in the result. 
Result so far: 32585.0
If we subtract 1290 from 1368, we get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 258

On to step 8:
258 goes into 789 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 325853.0
Subtracting 774 from 789 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
258 goes into 150 0 times with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 325853.0
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
When dividing 1500 by 258, we get 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 325853.05
Subtract 1290 from 1500 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 11:
258 goes into 2100 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 325853.058
Subtract 2064 from 2100 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
360 divided by 258 is 1 with a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 325853.0581
The remainder is 102 after subtracting 258 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 13:
1020 divided by 258 is 3 with a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 325853.05813
The remainder is 246 after subtracting 774 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 14:
When dividing 2460 by 258, we get 9 with a remainder of 138.
Use 9 as the next digit of our solution. 
Result so far: 325853.058139
If we subtract 2322 from 2460, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 15:
The number 258 fits into 1380 5 times, leaving a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 325853.0581395
Subtracting 1290 from 1380 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 16:
900 divided by 258 is 3 with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 325853.05813953
Subtract 774 from 900 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

After the division, we end up with 325853.05813953 and a remainder of 1.26e-07.
