56156590 ÷ 516 
The aim is to understand the frequency of 516 in 56156590.

Let's proceed to step 1:
516 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 516

Going ahead to step 2:
56 divided by 516 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 516

Advancing to step 3:
If we divide 561 by 516, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 45 after subtracting 516 from 561.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 516

On to step 4:
455 divided by 516 is 0 with a remainder of 455.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 455, we end up with 455.
Take the next digit (6) from the dividend and append it to 455, then repeat: 4556 / 516

Moving on to step 5:
The number 516 fits into 4556 8 times, leaving a remainder of 428.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtracting 4128 from 4556 leaves us with 428.
Fetch the next digit (5) from the dividend, attach it to 428 and continue: 4285 / 516

Moving on to step 6:
If we divide 4285 by 516, we get 8 and a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 1088.0
Subtract 4128 from 4285 to get 157.
Grab the next digit (9) from the dividend, add it to 157, then carry on: 1579 / 516

On to step 7:
The number 516 fits into 1579 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 10883.0
The remainder is 31 after subtracting 1548 from 1579.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 516

Advancing to step 8:
The number 516 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 108830.0
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 9:
516 can be fit into 3100 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 108830.6
If we take 3096 away from 3100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
40 divided by 516 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 108830.6
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 516, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 108830.6
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 108830.6 and a remainder of 0.04.
