6158887 ÷ 722 
The aim is to understand the frequency of 722 in 6158887.

Moving on to step 1:
If we divide 6 by 722, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 722

Advancing to step 2:
If we divide 61 by 722, we get 0 and a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 722

Going ahead to step 3:
When dividing 615 by 722, we get 0 with a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 615, we get 615.
Fetch the next digit (8) from the dividend, attach it to 615 and continue: 6158 / 722

Advancing to step 4:
When dividing 6158 by 722, we get 8 with a remainder of 382.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5776 from 6158 to get 382.
Take the next digit (8) from the dividend and append it to 382, then repeat: 3828 / 722

Moving on to step 5:
When dividing 3828 by 722, we get 5 with a remainder of 218.
Write down 5 as next digit of the result. 
Result so far: 85.0
Deduct 3610 from 3828 and we're left with 218.
Bring next digit (8) of the dividend behind the 218 and repeat the process: 2188 / 722

On to step 6:
If we divide 2188 by 722, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 853.0
The remainder is 22 after subtracting 2166 from 2188.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 722

Advancing to step 7:
722 can be fit into 227 0 times, resulting in a remainder of 227.
Use 0 as the next digit of our solution. 
Result so far: 8530.0
The remainder is 227 after subtracting 0 from 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 8:
722 can be fit into 2270 3 times, resulting in a remainder of 104.
Use 3 as the next digit of our solution. 
Result so far: 8530.3
If we subtract 2166 from 2270, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
722 can be fit into 1040 1 times, resulting in a remainder of 318.
The number 1 becomes the next digit in our result. 
Result so far: 8530.31
The remainder is 318 after subtracting 722 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 10:
If we divide 3180 by 722, we get 4 and a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 8530.314
If we take 2888 away from 3180, we end up 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.

Let's proceed to step 11:
722 goes into 2920 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 8530.3144
Subtract 2888 from 2920 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 8530.3144, with a leftover of 0.00032.
