We divide 57671673 by 891
The aim is to understand the frequency of 891 in 57671673.

Step 1:
If we divide 5 by 891, we get 0 and 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.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 891

Let's proceed to step 2:
If we divide 57 by 891, we get 0 and a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 891

Going ahead to step 3:
891 can be fit into 576 0 times, resulting in a remainder of 576.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 576 to get 576.
Include the next digit (7) from the dividend after 576, then repeat: 5767 / 891

Advancing to step 4:
5767 divided by 891 is 6 with a remainder of 421.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5346 from 5767 leaves us with 421.
Take the next digit (1) from the dividend and append it to 421, then repeat: 4211 / 891

Let's proceed to step 5:
The number 891 fits into 4211 4 times, leaving a remainder of 647.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 3564 from 4211, we get 647.
Bring next digit (6) of the dividend behind the 647 and repeat the process: 6476 / 891

On to step 6:
891 can be fit into 6476 7 times, resulting in a remainder of 239.
Put 7 as the next digit of the answer. 
Result so far: 647.0
If we subtract 6237 from 6476, we get 239.
Bring next digit (7) of the dividend behind the 239 and repeat the process: 2397 / 891

Advancing to step 7:
891 goes into 2397 2 times with a remainder of 615.
Put 2 as the next digit of the answer. 
Result so far: 6472.0
Deduct 1782 from 2397 and we're left with 615.
Include the next digit (3) from the dividend after 615, then repeat: 6153 / 891

Going ahead to step 8:
891 goes into 6153 6 times with a remainder of 807.
Write down 6 as next digit of the result. 
Result so far: 64726.0
Deduct 5346 from 6153 and we're left with 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Advancing to step 9:
891 can be fit into 8070 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 64726.9
Deduct 8019 from 8070 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
891 goes into 510 0 times with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 64726.9
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 11:
891 can be fit into 5100 5 times, resulting in a remainder of 645.
Record the quotient 5 as the next digit in the result. 
Result so far: 64726.905
Deduct 4455 from 5100 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 12:
If we divide 6450 by 891, we get 7 and a remainder of 213.
The number 7 becomes the next digit in our result. 
Result so far: 64726.9057
Subtract 6237 from 6450 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 13:
2130 divided by 891 is 2 with a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 64726.90572
If we take 1782 away from 2130, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 14:
891 goes into 3480 3 times with a remainder of 807.
The number 3 becomes the next digit in our result. 
Result so far: 64726.905723
If we subtract 2673 from 3480, we get 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Moving on to step 15:
8070 divided by 891 is 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 64726.9057239
The remainder is 51 after subtracting 8019 from 8070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 16:
510 divided by 891 is 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 64726.9057239
If we subtract 0 from 510, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

After the division, we end up with 64726.9057239 and a remainder of 5.1e-07.
