We divide 13996077 by 887
The aim is to understand the frequency of 887 in 13996077.

Advancing to step 1:
1 divided by 887 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 887

Going ahead to step 2:
When dividing 13 by 887, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 887

Let's proceed to step 3:
887 can be fit into 139 0 times, resulting in a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 887

Step 4:
887 can be fit into 1399 1 times, resulting in a remainder of 512.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 887 from 1399 leaves us with 512.
Include the next digit (6) from the dividend after 512, then repeat: 5126 / 887

Advancing to step 5:
When dividing 5126 by 887, we get 5 with a remainder of 691.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 4435 from 5126 and we're left with 691.
Grab the next digit (0) from the dividend, add it to 691, then carry on: 6910 / 887

Going ahead to step 6:
If we divide 6910 by 887, we get 7 and a remainder of 701.
The next digit of our result is 7. 
Result so far: 157.0
The remainder is 701 after subtracting 6209 from 6910.
Fetch the next digit (7) from the dividend, attach it to 701 and continue: 7017 / 887

Let's proceed to step 7:
If we divide 7017 by 887, we get 7 and a remainder of 808.
Record the quotient 7 as the next digit in the result. 
Result so far: 1577.0
Subtract 6209 from 7017 to get 808.
Grab the next digit (7) from the dividend, add it to 808, then carry on: 8087 / 887

Moving on to step 8:
If we divide 8087 by 887, we get 9 and a remainder of 104.
The next digit of our result is 9. 
Result so far: 15779.0
If we take 7983 away from 8087, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
The number 887 fits into 1040 1 times, leaving a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 15779.1
If we take 887 away from 1040, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 10:
If we divide 1530 by 887, we get 1 and a remainder of 643.
Put 1 as the next digit of the answer. 
Result so far: 15779.11
The remainder is 643 after subtracting 887 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

In conclusion, the division gives 15779.11 with a balance of 0.643.
