91706573 ÷ 516 
The aim is to understand the frequency of 516 in 91706573.

Going ahead to step 1:
9 divided by 516 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 516

On to step 2:
516 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 516

Let's proceed to step 3:
917 divided by 516 is 1 with a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 401 after subtracting 516 from 917.
Fetch the next digit (0) from the dividend, attach it to 401 and continue: 4010 / 516

Advancing to step 4:
4010 divided by 516 is 7 with a remainder of 398.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 3612 from 4010 and we're left with 398.
Take the next digit (6) from the dividend and append it to 398, then repeat: 3986 / 516

On to step 5:
516 can be fit into 3986 7 times, resulting in a remainder of 374.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we subtract 3612 from 3986, we get 374.
Take the next digit (5) from the dividend and append it to 374, then repeat: 3745 / 516

Moving on to step 6:
The number 516 fits into 3745 7 times, leaving a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 1777.0
Subtracting 3612 from 3745 leaves us with 133.
Grab the next digit (7) from the dividend, add it to 133, then carry on: 1337 / 516

Advancing to step 7:
516 goes into 1337 2 times with a remainder of 305.
Put 2 as the next digit of the answer. 
Result so far: 17772.0
If we take 1032 away from 1337, we end up with 305.
Bring next digit (3) of the dividend behind the 305 and repeat the process: 3053 / 516

Advancing to step 8:
When dividing 3053 by 516, we get 5 with a remainder of 473.
Use 5 as the next digit of our solution. 
Result so far: 177725.0
Deduct 2580 from 3053 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 9:
516 can be fit into 4730 9 times, resulting in a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 177725.9
Subtracting 4644 from 4730 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 10:
When dividing 860 by 516, we get 1 with a remainder of 344.
The number 1 becomes the next digit in our result. 
Result so far: 177725.91
If we take 516 away from 860, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 11:
The number 516 fits into 3440 6 times, leaving a remainder of 344.
Put 6 as the next digit of the answer. 
Result so far: 177725.916
Deduct 3096 from 3440 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 12:
The number 516 fits into 3440 6 times, leaving a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 177725.9166
If we take 3096 away from 3440, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 177725.9166 and a remainder of 0.00344.
