23583418 divided by 891 
The aim is to understand the frequency of 891 in 23583418.

On to step 1:
The number 891 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 891

Moving on to step 2:
23 divided by 891 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 891

Step 3:
If we divide 235 by 891, we get 0 and a remainder of 235.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 235 and we're left with 235.
Include the next digit (8) from the dividend after 235, then repeat: 2358 / 891

Going ahead to step 4:
891 goes into 2358 2 times with a remainder of 576.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1782 from 2358 and we're left with 576.
Fetch the next digit (3) from the dividend, attach it to 576 and continue: 5763 / 891

Advancing to step 5:
The number 891 fits into 5763 6 times, leaving a remainder of 417.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 5346 from 5763, we get 417.
Grab the next digit (4) from the dividend, add it to 417, then carry on: 4174 / 891

Step 6:
891 goes into 4174 4 times with a remainder of 610.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
If we take 3564 away from 4174, we end up with 610.
Take the next digit (1) from the dividend and append it to 610, then repeat: 6101 / 891

Advancing to step 7:
The number 891 fits into 6101 6 times, leaving a remainder of 755.
Use 6 as the next digit of our solution. 
Result so far: 2646.0
Deduct 5346 from 6101 and we're left with 755.
Fetch the next digit (8) from the dividend, attach it to 755 and continue: 7558 / 891

Step 8:
891 goes into 7558 8 times with a remainder of 430.
Use 8 as the next digit of our solution. 
Result so far: 26468.0
The remainder is 430 after subtracting 7128 from 7558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 9:
If we divide 4300 by 891, we get 4 and a remainder of 736.
Write down 4 as next digit of the result. 
Result so far: 26468.4
If we subtract 3564 from 4300, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 10:
891 can be fit into 7360 8 times, resulting in a remainder of 232.
Write down 8 as next digit of the result. 
Result so far: 26468.48
Subtract 7128 from 7360 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 11:
If we divide 2320 by 891, we get 2 and a remainder of 538.
Write down 2 as next digit of the result. 
Result so far: 26468.482
If we subtract 1782 from 2320, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

On to step 12:
The number 891 fits into 5380 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 26468.4826
Subtracting 5346 from 5380 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
891 goes into 340 0 times with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 26468.4826
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 14:
891 can be fit into 3400 3 times, resulting in a remainder of 727.
Use 3 as the next digit of our solution. 
Result so far: 26468.482603
Deduct 2673 from 3400 and we're left with 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Advancing to step 15:
7270 divided by 891 is 8 with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 26468.4826038
If we subtract 7128 from 7270, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 16:
891 can be fit into 1420 1 times, resulting in a remainder of 529.
Use 1 as the next digit of our solution. 
Result so far: 26468.48260381
If we subtract 891 from 1420, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

After the division, we end up with 26468.48260381 and a remainder of 5.29e-07.
