We're dividing 39489285 by 921 
The aim is to understand the frequency of 921 in 39489285.

Step 1:
921 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 921

Going ahead to step 2:
The number 921 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 921

Advancing to step 3:
921 can be fit into 394 0 times, resulting in a remainder of 394.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 394, we end up with 394.
Bring next digit (8) of the dividend behind the 394 and repeat the process: 3948 / 921

On to step 4:
If we divide 3948 by 921, we get 4 and a remainder of 264.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3684 from 3948 leaves us with 264.
Fetch the next digit (9) from the dividend, attach it to 264 and continue: 2649 / 921

Moving on to step 5:
If we divide 2649 by 921, we get 2 and a remainder of 807.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 1842 from 2649 leaves us with 807.
Fetch the next digit (2) from the dividend, attach it to 807 and continue: 8072 / 921

Going ahead to step 6:
8072 divided by 921 is 8 with a remainder of 704.
The next digit of our result is 8. 
Result so far: 428.0
The remainder is 704 after subtracting 7368 from 8072.
Include the next digit (8) from the dividend after 704, then repeat: 7048 / 921

On to step 7:
When dividing 7048 by 921, we get 7 with a remainder of 601.
Use 7 as the next digit of our solution. 
Result so far: 4287.0
If we subtract 6447 from 7048, we get 601.
Append the next digit (5) from the dividend to 601 and continue with: 6015 / 921

Moving on to step 8:
921 can be fit into 6015 6 times, resulting in a remainder of 489.
The next digit of our result is 6. 
Result so far: 42876.0
Subtract 5526 from 6015 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 9:
If we divide 4890 by 921, we get 5 and a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 42876.5
If we take 4605 away from 4890, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 10:
When dividing 2850 by 921, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 42876.53
Subtract 2763 from 2850 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
When dividing 870 by 921, we get 0 with a remainder of 870.
The number 0 becomes the next digit in our result. 
Result so far: 42876.53
Subtract 0 from 870 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Moving on to step 12:
921 goes into 8700 9 times with a remainder of 411.
The number 9 becomes the next digit in our result. 
Result so far: 42876.5309
Subtracting 8289 from 8700 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Moving on to step 13:
The number 921 fits into 4110 4 times, leaving a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 42876.53094
If we subtract 3684 from 4110, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 14:
4260 divided by 921 is 4 with a remainder of 576.
The number 4 becomes the next digit in our result. 
Result so far: 42876.530944
The remainder is 576 after subtracting 3684 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The quotient of the division is 42876.530944, and the remainder is 5.76e-05.
