90622928 divided by 838 
The aim is to understand the frequency of 838 in 90622928.

On to step 1:
The number 838 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 838

On to step 2:
If we divide 90 by 838, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 838

Going ahead to step 3:
The number 838 fits into 906 1 times, leaving a remainder of 68.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 838 from 906, we get 68.
Fetch the next digit (2) from the dividend, attach it to 68 and continue: 682 / 838

Moving on to step 4:
When dividing 682 by 838, we get 0 with a remainder of 682.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 682, we end up with 682.
Grab the next digit (2) from the dividend, add it to 682, then carry on: 6822 / 838

Going ahead to step 5:
838 can be fit into 6822 8 times, resulting in a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 6704 from 6822, we get 118.
Include the next digit (9) from the dividend after 118, then repeat: 1189 / 838

On to step 6:
838 goes into 1189 1 times with a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 1081.0
Subtract 838 from 1189 to get 351.
Grab the next digit (2) from the dividend, add it to 351, then carry on: 3512 / 838

Let's proceed to step 7:
If we divide 3512 by 838, we get 4 and a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 10814.0
Deduct 3352 from 3512 and we're left with 160.
Fetch the next digit (8) from the dividend, attach it to 160 and continue: 1608 / 838

On to step 8:
If we divide 1608 by 838, we get 1 and a remainder of 770.
Put 1 as the next digit of the answer. 
Result so far: 108141.0
If we subtract 838 from 1608, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 9:
838 goes into 7700 9 times with a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 108141.9
Deduct 7542 from 7700 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
838 goes into 1580 1 times with a remainder of 742.
Use 1 as the next digit of our solution. 
Result so far: 108141.91
If we take 838 away from 1580, we end up with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Step 11:
838 can be fit into 7420 8 times, resulting in a remainder of 716.
The number 8 becomes the next digit in our result. 
Result so far: 108141.918
Subtract 6704 from 7420 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 12:
838 can be fit into 7160 8 times, resulting in a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 108141.9188
If we take 6704 away from 7160, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The quotient of the division is 108141.9188, and the remainder is 0.00456.
