We divide 21403417 by 586
The aim is to understand the frequency of 586 in 21403417.

Going ahead to step 1:
2 divided by 586 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 586

Advancing to step 2:
When dividing 21 by 586, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 586

Going ahead to step 3:
214 divided by 586 is 0 with a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 214, we end up with 214.
Bring next digit (0) of the dividend behind the 214 and repeat the process: 2140 / 586

Let's proceed to step 4:
586 can be fit into 2140 3 times, resulting in a remainder of 382.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1758 from 2140 to get 382.
Append the next digit (3) from the dividend to 382 and continue with: 3823 / 586

Step 5:
The number 586 fits into 3823 6 times, leaving a remainder of 307.
The next digit of our result is 6. 
Result so far: 36.0
If we take 3516 away from 3823, we end up with 307.
Bring next digit (4) of the dividend behind the 307 and repeat the process: 3074 / 586

Going ahead to step 6:
586 can be fit into 3074 5 times, resulting in a remainder of 144.
Record the quotient 5 as the next digit in the result. 
Result so far: 365.0
If we take 2930 away from 3074, we end up with 144.
Append the next digit (1) from the dividend to 144 and continue with: 1441 / 586

Going ahead to step 7:
The number 586 fits into 1441 2 times, leaving a remainder of 269.
Put 2 as the next digit of the answer. 
Result so far: 3652.0
If we subtract 1172 from 1441, we get 269.
Append the next digit (7) from the dividend to 269 and continue with: 2697 / 586

Let's proceed to step 8:
586 can be fit into 2697 4 times, resulting in a remainder of 353.
Use 4 as the next digit of our solution. 
Result so far: 36524.0
Subtracting 2344 from 2697 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 9:
The number 586 fits into 3530 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 36524.6
If we subtract 3516 from 3530, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
When dividing 140 by 586, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 36524.6
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
When dividing 1400 by 586, we get 2 with a remainder of 228.
The next digit of our result is 2. 
Result so far: 36524.602
Subtract 1172 from 1400 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 12:
2280 divided by 586 is 3 with a remainder of 522.
Put 3 as the next digit of the answer. 
Result so far: 36524.6023
If we subtract 1758 from 2280, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 13:
If we divide 5220 by 586, we get 8 and a remainder of 532.
Record the quotient 8 as the next digit in the result. 
Result so far: 36524.60238
The remainder is 532 after subtracting 4688 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 14:
5320 divided by 586 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 36524.602389
Subtracting 5274 from 5320 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
586 goes into 460 0 times with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 36524.602389
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 16:
4600 divided by 586 is 7 with a remainder of 498.
Write down 7 as next digit of the result. 
Result so far: 36524.60238907
Subtracting 4102 from 4600 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

The quotient of the division is 36524.60238907, and the remainder is 4.98e-07.
