We divide 90818212 by 787
The aim is to understand the frequency of 787 in 90818212.

Advancing to step 1:
If we divide 9 by 787, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 787

On to step 2:
787 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 787

Moving on to step 3:
787 can be fit into 908 1 times, resulting in a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 787 from 908, we get 121.
Take the next digit (1) from the dividend and append it to 121, then repeat: 1211 / 787

Moving on to step 4:
The number 787 fits into 1211 1 times, leaving a remainder of 424.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 787 from 1211, we get 424.
Take the next digit (8) from the dividend and append it to 424, then repeat: 4248 / 787

Let's proceed to step 5:
If we divide 4248 by 787, we get 5 and a remainder of 313.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 3935 from 4248 leaves us with 313.
Grab the next digit (2) from the dividend, add it to 313, then carry on: 3132 / 787

Moving on to step 6:
If we divide 3132 by 787, we get 3 and a remainder of 771.
The number 3 becomes the next digit in our result. 
Result so far: 1153.0
Deduct 2361 from 3132 and we're left with 771.
Take the next digit (1) from the dividend and append it to 771, then repeat: 7711 / 787

Let's proceed to step 7:
When dividing 7711 by 787, we get 9 with a remainder of 628.
Record the quotient 9 as the next digit in the result. 
Result so far: 11539.0
Subtract 7083 from 7711 to get 628.
Bring next digit (2) of the dividend behind the 628 and repeat the process: 6282 / 787

On to step 8:
If we divide 6282 by 787, we get 7 and a remainder of 773.
The next digit of our result is 7. 
Result so far: 115397.0
If we take 5509 away from 6282, we end up with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Moving on to step 9:
When dividing 7730 by 787, we get 9 with a remainder of 647.
Record the quotient 9 as the next digit in the result. 
Result so far: 115397.9
If we subtract 7083 from 7730, we get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Let's proceed to step 10:
If we divide 6470 by 787, we get 8 and a remainder of 174.
Write down 8 as next digit of the result. 
Result so far: 115397.98
The remainder is 174 after subtracting 6296 from 6470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 11:
The number 787 fits into 1740 2 times, leaving a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 115397.982
Subtract 1574 from 1740 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 12:
787 goes into 1660 2 times with a remainder of 86.
The next digit of our result is 2. 
Result so far: 115397.9822
The remainder is 86 after subtracting 1574 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 115397.9822, and the remainder is 0.00086.
