We look at the division of 87487241 by 358 
The aim is to understand the frequency of 358 in 87487241.

Step 1:
When dividing 8 by 358, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 358

On to step 2:
358 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 358

Moving on to step 3:
874 divided by 358 is 2 with a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 716 away from 874, we end up with 158.
Include the next digit (8) from the dividend after 158, then repeat: 1588 / 358

Step 4:
The number 358 fits into 1588 4 times, leaving a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1432 away from 1588, we end up with 156.
Take the next digit (7) from the dividend and append it to 156, then repeat: 1567 / 358

Advancing to step 5:
358 can be fit into 1567 4 times, resulting in a remainder of 135.
Write down 4 as next digit of the result. 
Result so far: 244.0
Subtracting 1432 from 1567 leaves us with 135.
Grab the next digit (2) from the dividend, add it to 135, then carry on: 1352 / 358

Going ahead to step 6:
If we divide 1352 by 358, we get 3 and a remainder of 278.
Put 3 as the next digit of the answer. 
Result so far: 2443.0
Subtract 1074 from 1352 to get 278.
Bring next digit (4) of the dividend behind the 278 and repeat the process: 2784 / 358

Going ahead to step 7:
If we divide 2784 by 358, we get 7 and a remainder of 278.
Record the quotient 7 as the next digit in the result. 
Result so far: 24437.0
Deduct 2506 from 2784 and we're left with 278.
Grab the next digit (1) from the dividend, add it to 278, then carry on: 2781 / 358

Let's proceed to step 8:
2781 divided by 358 is 7 with a remainder of 275.
Write down 7 as next digit of the result. 
Result so far: 244377.0
Subtract 2506 from 2781 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 9:
When dividing 2750 by 358, we get 7 with a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 244377.7
If we take 2506 away from 2750, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
2440 divided by 358 is 6 with a remainder of 292.
Use 6 as the next digit of our solution. 
Result so far: 244377.76
Deduct 2148 from 2440 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 11:
358 goes into 2920 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 244377.768
If we subtract 2864 from 2920, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
When dividing 560 by 358, we get 1 with a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 244377.7681
Deduct 358 from 560 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 13:
When dividing 2020 by 358, we get 5 with a remainder of 230.
The next digit of our result is 5. 
Result so far: 244377.76815
If we take 1790 away from 2020, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
The number 358 fits into 2300 6 times, leaving a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 244377.768156
Subtracting 2148 from 2300 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 15:
358 can be fit into 1520 4 times, resulting in a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 244377.7681564
Deduct 1432 from 1520 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 16:
If we divide 880 by 358, we get 2 and a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 244377.76815642
Subtracting 716 from 880 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The quotient of the division is 244377.76815642, and the remainder is 1.64e-07.
