We look at the division of 7678883 by 586 
The aim is to understand the frequency of 586 in 7678883.

On to step 1:
If we divide 7 by 586, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 586

Moving on to step 2:
586 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 586

Step 3:
The number 586 fits into 767 1 times, leaving a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 586 from 767 leaves us with 181.
Grab the next digit (8) from the dividend, add it to 181, then carry on: 1818 / 586

Advancing to step 4:
When dividing 1818 by 586, we get 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1758 from 1818 and we're left with 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 586

Step 5:
If we divide 608 by 586, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 131.0
If we subtract 586 from 608, we get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 586

Let's proceed to step 6:
228 divided by 586 is 0 with a remainder of 228.
Use 0 as the next digit of our solution. 
Result so far: 1310.0
If we subtract 0 from 228, we get 228.
Take the next digit (3) from the dividend and append it to 228, then repeat: 2283 / 586

Moving on to step 7:
586 can be fit into 2283 3 times, resulting in a remainder of 525.
Put 3 as the next digit of the answer. 
Result so far: 13103.0
If we take 1758 away from 2283, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 8:
586 can be fit into 5250 8 times, resulting in a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 13103.8
If we take 4688 away from 5250, we end up with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 9:
When dividing 5620 by 586, we get 9 with a remainder of 346.
Record the quotient 9 as the next digit in the result. 
Result so far: 13103.89
If we subtract 5274 from 5620, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 10:
586 can be fit into 3460 5 times, resulting in a remainder of 530.
The next digit of our result is 5. 
Result so far: 13103.895
The remainder is 530 after subtracting 2930 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 11:
586 can be fit into 5300 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 13103.8959
Deduct 5274 from 5300 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
The number 586 fits into 260 0 times, leaving a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 13103.8959
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
2600 divided by 586 is 4 with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 13103.895904
Subtract 2344 from 2600 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 14:
If we divide 2560 by 586, we get 4 and a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 13103.8959044
If we take 2344 away from 2560, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The quotient of the division is 13103.8959044, and the remainder is 2.16e-06.
