3300370 ÷ 899 
The aim is to understand the frequency of 899 in 3300370.

Going ahead to step 1:
If we divide 3 by 899, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 899

Step 2:
899 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 899

Moving on to step 3:
899 can be fit into 330 0 times, resulting in a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 330 leaves us with 330.
Include the next digit (0) from the dividend after 330, then repeat: 3300 / 899

Let's proceed to step 4:
When dividing 3300 by 899, we get 3 with a remainder of 603.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2697 from 3300 to get 603.
Bring next digit (3) of the dividend behind the 603 and repeat the process: 6033 / 899

Going ahead to step 5:
6033 divided by 899 is 6 with a remainder of 639.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 5394 from 6033 and we're left with 639.
Include the next digit (7) from the dividend after 639, then repeat: 6397 / 899

Moving on to step 6:
6397 divided by 899 is 7 with a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 367.0
Subtract 6293 from 6397 to get 104.
Bring next digit (0) of the dividend behind the 104 and repeat the process: 1040 / 899

On to step 7:
899 can be fit into 1040 1 times, resulting in a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 3671.0
The remainder is 141 after subtracting 899 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 8:
If we divide 1410 by 899, we get 1 and a remainder of 511.
Use 1 as the next digit of our solution. 
Result so far: 3671.1
If we take 899 away from 1410, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 9:
899 can be fit into 5110 5 times, resulting in a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 3671.15
If we take 4495 away from 5110, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 10:
The number 899 fits into 6150 6 times, leaving a remainder of 756.
Use 6 as the next digit of our solution. 
Result so far: 3671.156
Deduct 5394 from 6150 and we're left with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Moving on to step 11:
The number 899 fits into 7560 8 times, leaving a remainder of 368.
Record the quotient 8 as the next digit in the result. 
Result so far: 3671.1568
Deduct 7192 from 7560 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 12:
The number 899 fits into 3680 4 times, leaving a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 3671.15684
Subtracting 3596 from 3680 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
899 can be fit into 840 0 times, resulting in a remainder of 840.
Use 0 as the next digit of our solution. 
Result so far: 3671.15684
If we take 0 away from 840, we end up with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 14:
899 can be fit into 8400 9 times, resulting in a remainder of 309.
Write down 9 as next digit of the result. 
Result so far: 3671.1568409
Subtract 8091 from 8400 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 15:
3090 divided by 899 is 3 with a remainder of 393.
Put 3 as the next digit of the answer. 
Result so far: 3671.15684093
Subtracting 2697 from 3090 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

The final outcome is 3671.15684093, with a leftover of 3.93e-07.
