We divide 78839881 by 905
The aim is to understand the frequency of 905 in 78839881.

On to step 1:
The number 905 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 905

Going ahead to step 2:
If we divide 78 by 905, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 905

Going ahead to step 3:
905 can be fit into 788 0 times, resulting in a remainder of 788.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 788 leaves us with 788.
Grab the next digit (3) from the dividend, add it to 788, then carry on: 7883 / 905

Let's proceed to step 4:
When dividing 7883 by 905, we get 8 with a remainder of 643.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7240 from 7883 and we're left with 643.
Bring next digit (9) of the dividend behind the 643 and repeat the process: 6439 / 905

Let's proceed to step 5:
905 can be fit into 6439 7 times, resulting in a remainder of 104.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 6335 from 6439 to get 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 905

Step 6:
905 can be fit into 1048 1 times, resulting in a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 871.0
The remainder is 143 after subtracting 905 from 1048.
Bring next digit (8) of the dividend behind the 143 and repeat the process: 1438 / 905

Going ahead to step 7:
1438 divided by 905 is 1 with a remainder of 533.
Put 1 as the next digit of the answer. 
Result so far: 8711.0
Subtracting 905 from 1438 leaves us with 533.
Fetch the next digit (1) from the dividend, attach it to 533 and continue: 5331 / 905

On to step 8:
905 can be fit into 5331 5 times, resulting in a remainder of 806.
Put 5 as the next digit of the answer. 
Result so far: 87115.0
If we subtract 4525 from 5331, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Moving on to step 9:
905 can be fit into 8060 8 times, resulting in a remainder of 820.
Record the quotient 8 as the next digit in the result. 
Result so far: 87115.8
If we subtract 7240 from 8060, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 10:
If we divide 8200 by 905, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 87115.89
Subtracting 8145 from 8200 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 11:
550 divided by 905 is 0 with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 87115.89
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 12:
905 can be fit into 5500 6 times, resulting in a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 87115.8906
If we take 5430 away from 5500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
905 goes into 700 0 times with a remainder of 700.
The next digit of our result is 0. 
Result so far: 87115.8906
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 14:
7000 divided by 905 is 7 with a remainder of 665.
Put 7 as the next digit of the answer. 
Result so far: 87115.890607
If we take 6335 away from 7000, we end up 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:
6650 divided by 905 is 7 with a remainder of 315.
Use 7 as the next digit of our solution. 
Result so far: 87115.8906077
If we subtract 6335 from 6650, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final outcome is 87115.8906077, with a leftover of 3.15e-06.
