We divide 51264817 by 899
The aim is to understand the frequency of 899 in 51264817.

On to step 1:
If we divide 5 by 899, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 899

Moving on to step 2:
When dividing 51 by 899, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 899

Moving on to step 3:
899 can be fit into 512 0 times, resulting in a remainder of 512.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Grab the next digit (6) from the dividend, add it to 512, then carry on: 5126 / 899

Moving on to step 4:
When dividing 5126 by 899, we get 5 with a remainder of 631.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4495 from 5126 to get 631.
Bring next digit (4) of the dividend behind the 631 and repeat the process: 6314 / 899

Advancing to step 5:
The number 899 fits into 6314 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Deduct 6293 from 6314 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 899

Step 6:
If we divide 218 by 899, we get 0 and a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 570.0
Deduct 0 from 218 and we're left with 218.
Take the next digit (1) from the dividend and append it to 218, then repeat: 2181 / 899

Step 7:
The number 899 fits into 2181 2 times, leaving a remainder of 383.
Use 2 as the next digit of our solution. 
Result so far: 5702.0
If we subtract 1798 from 2181, we get 383.
Bring next digit (7) of the dividend behind the 383 and repeat the process: 3837 / 899

Moving on to step 8:
3837 divided by 899 is 4 with a remainder of 241.
Put 4 as the next digit of the answer. 
Result so far: 57024.0
Subtract 3596 from 3837 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 9:
899 can be fit into 2410 2 times, resulting in a remainder of 612.
Write down 2 as next digit of the result. 
Result so far: 57024.2
If we subtract 1798 from 2410, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 10:
899 can be fit into 6120 6 times, resulting in a remainder of 726.
Put 6 as the next digit of the answer. 
Result so far: 57024.26
Deduct 5394 from 6120 and we're left with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Step 11:
899 goes into 7260 8 times with a remainder of 68.
The next digit of our result is 8. 
Result so far: 57024.268
Subtracting 7192 from 7260 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
The number 899 fits into 680 0 times, leaving a remainder of 680.
Record the quotient 0 as the next digit in the result. 
Result so far: 57024.268
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
The number 899 fits into 6800 7 times, leaving a remainder of 507.
The number 7 becomes the next digit in our result. 
Result so far: 57024.26807
Subtract 6293 from 6800 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 14:
5070 divided by 899 is 5 with a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 57024.268075
Deduct 4495 from 5070 and we're left with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 15:
5750 divided by 899 is 6 with a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 57024.2680756
Subtracting 5394 from 5750 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 16:
899 goes into 3560 3 times with a remainder of 863.
Record the quotient 3 as the next digit in the result. 
Result so far: 57024.26807563
If we subtract 2697 from 3560, we get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

The final outcome is 57024.26807563, with a leftover of 8.63e-07.
