87682391 divided by 899 
The aim is to understand the frequency of 899 in 87682391.

Let's proceed to step 1:
899 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 899

Step 2:
87 divided by 899 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 899

Moving on to step 3:
If we divide 876 by 899, we get 0 and a remainder of 876.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 876 after subtracting 0 from 876.
Fetch the next digit (8) from the dividend, attach it to 876 and continue: 8768 / 899

Step 4:
The number 899 fits into 8768 9 times, leaving a remainder of 677.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 8091 from 8768 leaves us with 677.
Fetch the next digit (2) from the dividend, attach it to 677 and continue: 6772 / 899

Step 5:
899 goes into 6772 7 times with a remainder of 479.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Subtract 6293 from 6772 to get 479.
Fetch the next digit (3) from the dividend, attach it to 479 and continue: 4793 / 899

Step 6:
899 can be fit into 4793 5 times, resulting in a remainder of 298.
Record the quotient 5 as the next digit in the result. 
Result so far: 975.0
Subtracting 4495 from 4793 leaves us with 298.
Grab the next digit (9) from the dividend, add it to 298, then carry on: 2989 / 899

Going ahead to step 7:
If we divide 2989 by 899, we get 3 and a remainder of 292.
Write down 3 as next digit of the result. 
Result so far: 9753.0
Deduct 2697 from 2989 and we're left with 292.
Append the next digit (1) from the dividend to 292 and continue with: 2921 / 899

Advancing to step 8:
When dividing 2921 by 899, we get 3 with a remainder of 224.
Record the quotient 3 as the next digit in the result. 
Result so far: 97533.0
Deduct 2697 from 2921 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 9:
2240 divided by 899 is 2 with a remainder of 442.
Use 2 as the next digit of our solution. 
Result so far: 97533.2
Subtracting 1798 from 2240 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 10:
899 goes into 4420 4 times with a remainder of 824.
Write down 4 as next digit of the result. 
Result so far: 97533.24
Subtract 3596 from 4420 to get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Step 11:
The number 899 fits into 8240 9 times, leaving a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 97533.249
If we take 8091 away from 8240, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 12:
If we divide 1490 by 899, we get 1 and a remainder of 591.
Write down 1 as next digit of the result. 
Result so far: 97533.2491
Deduct 899 from 1490 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 13:
When dividing 5910 by 899, we get 6 with a remainder of 516.
Write down 6 as next digit of the result. 
Result so far: 97533.24916
Deduct 5394 from 5910 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 14:
5160 divided by 899 is 5 with a remainder of 665.
The next digit of our result is 5. 
Result so far: 97533.249165
Subtracting 4495 from 5160 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 15:
The number 899 fits into 6650 7 times, leaving a remainder of 357.
Record the quotient 7 as the next digit in the result. 
Result so far: 97533.2491657
Deduct 6293 from 6650 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 16:
The number 899 fits into 3570 3 times, leaving a remainder of 873.
Use 3 as the next digit of our solution. 
Result so far: 97533.24916573
Subtracting 2697 from 3570 leaves us with 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

The final outcome is 97533.24916573, with a leftover of 8.73e-07.
