85576845 ÷ 961 
The aim is to understand the frequency of 961 in 85576845.

On to step 1:
If we divide 8 by 961, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 961

Let's proceed to step 2:
If we divide 85 by 961, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 961

Moving on to step 3:
961 goes into 855 0 times with a remainder of 855.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 855 leaves us with 855.
Bring next digit (7) of the dividend behind the 855 and repeat the process: 8557 / 961

Advancing to step 4:
If we divide 8557 by 961, we get 8 and a remainder of 869.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 869 after subtracting 7688 from 8557.
Grab the next digit (6) from the dividend, add it to 869, then carry on: 8696 / 961

Let's proceed to step 5:
If we divide 8696 by 961, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 8649 from 8696 and we're left with 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 961

Let's proceed to step 6:
478 divided by 961 is 0 with a remainder of 478.
Put 0 as the next digit of the answer. 
Result so far: 890.0
Subtracting 0 from 478 leaves us with 478.
Take the next digit (4) from the dividend and append it to 478, then repeat: 4784 / 961

Moving on to step 7:
The number 961 fits into 4784 4 times, leaving a remainder of 940.
The number 4 becomes the next digit in our result. 
Result so far: 8904.0
If we take 3844 away from 4784, we end up with 940.
Grab the next digit (5) from the dividend, add it to 940, then carry on: 9405 / 961

On to step 8:
If we divide 9405 by 961, we get 9 and a remainder of 756.
Record the quotient 9 as the next digit in the result. 
Result so far: 89049.0
If we take 8649 away from 9405, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 9:
961 goes into 7560 7 times with a remainder of 833.
Record the quotient 7 as the next digit in the result. 
Result so far: 89049.7
Subtract 6727 from 7560 to get 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Going ahead to step 10:
961 can be fit into 8330 8 times, resulting in a remainder of 642.
The number 8 becomes the next digit in our result. 
Result so far: 89049.78
Subtracting 7688 from 8330 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 11:
If we divide 6420 by 961, we get 6 and a remainder of 654.
Write down 6 as next digit of the result. 
Result so far: 89049.786
If we take 5766 away from 6420, we end up with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 12:
961 can be fit into 6540 6 times, resulting in a remainder of 774.
Use 6 as the next digit of our solution. 
Result so far: 89049.7866
If we subtract 5766 from 6540, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

After the division, we end up with 89049.7866 and a remainder of 0.00774.
