16887408 ÷ 961 
The aim is to understand the frequency of 961 in 16887408.

Advancing to step 1:
When dividing 1 by 961, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 961

Moving on to step 2:
961 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 961

Moving on to step 3:
When dividing 168 by 961, we get 0 with a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 168, we get 168.
Bring next digit (8) of the dividend behind the 168 and repeat the process: 1688 / 961

Let's proceed to step 4:
The number 961 fits into 1688 1 times, leaving a remainder of 727.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 961 from 1688 and we're left with 727.
Take the next digit (7) from the dividend and append it to 727, then repeat: 7277 / 961

Moving on to step 5:
7277 divided by 961 is 7 with a remainder of 550.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 6727 from 7277, we get 550.
Grab the next digit (4) from the dividend, add it to 550, then carry on: 5504 / 961

Moving on to step 6:
961 can be fit into 5504 5 times, resulting in a remainder of 699.
The next digit of our result is 5. 
Result so far: 175.0
Deduct 4805 from 5504 and we're left with 699.
Bring next digit (0) of the dividend behind the 699 and repeat the process: 6990 / 961

Let's proceed to step 7:
961 can be fit into 6990 7 times, resulting in a remainder of 263.
The number 7 becomes the next digit in our result. 
Result so far: 1757.0
The remainder is 263 after subtracting 6727 from 6990.
Bring next digit (8) of the dividend behind the 263 and repeat the process: 2638 / 961

Advancing to step 8:
When dividing 2638 by 961, we get 2 with a remainder of 716.
The next digit of our result is 2. 
Result so far: 17572.0
Deduct 1922 from 2638 and we're left with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 9:
When dividing 7160 by 961, we get 7 with a remainder of 433.
The next digit of our result is 7. 
Result so far: 17572.7
The remainder is 433 after subtracting 6727 from 7160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 10:
The number 961 fits into 4330 4 times, leaving a remainder of 486.
The next digit of our result is 4. 
Result so far: 17572.74
Subtract 3844 from 4330 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 11:
961 can be fit into 4860 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 17572.745
The remainder is 55 after subtracting 4805 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
961 can be fit into 550 0 times, resulting in a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 17572.745
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 13:
If we divide 5500 by 961, we get 5 and a remainder of 695.
Write down 5 as next digit of the result. 
Result so far: 17572.74505
If we subtract 4805 from 5500, we get 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Going ahead to step 14:
961 can be fit into 6950 7 times, resulting in a remainder of 223.
Put 7 as the next digit of the answer. 
Result so far: 17572.745057
If we take 6727 away from 6950, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 15:
If we divide 2230 by 961, we get 2 and a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 17572.7450572
Deduct 1922 from 2230 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 16:
When dividing 3080 by 961, we get 3 with a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 17572.74505723
If we subtract 2883 from 3080, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Our division results in 17572.74505723 with a remaining 1.97e-07.
