37528989 divided by 586 
The aim is to understand the frequency of 586 in 37528989.

Going ahead to step 1:
586 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 586

Moving on to step 2:
37 divided by 586 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 586

Advancing to step 3:
If we divide 375 by 586, we get 0 and a remainder of 375.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 375 after subtracting 0 from 375.
Fetch the next digit (2) from the dividend, attach it to 375 and continue: 3752 / 586

Advancing to step 4:
586 goes into 3752 6 times with a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3516 from 3752 and we're left with 236.
Include the next digit (8) from the dividend after 236, then repeat: 2368 / 586

Advancing to step 5:
586 can be fit into 2368 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtracting 2344 from 2368 leaves us with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 586

Let's proceed to step 6:
When dividing 249 by 586, we get 0 with a remainder of 249.
Use 0 as the next digit of our solution. 
Result so far: 640.0
If we subtract 0 from 249, we get 249.
Take the next digit (8) from the dividend and append it to 249, then repeat: 2498 / 586

Moving on to step 7:
When dividing 2498 by 586, we get 4 with a remainder of 154.
The next digit of our result is 4. 
Result so far: 6404.0
If we take 2344 away from 2498, we end up with 154.
Bring next digit (9) of the dividend behind the 154 and repeat the process: 1549 / 586

Let's proceed to step 8:
If we divide 1549 by 586, we get 2 and a remainder of 377.
Record the quotient 2 as the next digit in the result. 
Result so far: 64042.0
Deduct 1172 from 1549 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
If we divide 3770 by 586, we get 6 and a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 64042.6
If we subtract 3516 from 3770, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 10:
2540 divided by 586 is 4 with a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 64042.64
Deduct 2344 from 2540 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 11:
The number 586 fits into 1960 3 times, leaving a remainder of 202.
The next digit of our result is 3. 
Result so far: 64042.643
If we take 1758 away from 1960, we end up 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.

Moving on to step 12:
586 goes into 2020 3 times with a remainder of 262.
The next digit of our result is 3. 
Result so far: 64042.6433
If we subtract 1758 from 2020, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

After the division, we end up with 64042.6433 and a remainder of 0.00262.
