We divide 31518336 by 921
The aim is to understand the frequency of 921 in 31518336.

Advancing to step 1:
If we divide 3 by 921, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 921

Advancing to step 2:
921 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 921

Going ahead to step 3:
If we divide 315 by 921, we get 0 and a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 315, we end up with 315.
Grab the next digit (1) from the dividend, add it to 315, then carry on: 3151 / 921

Moving on to step 4:
3151 divided by 921 is 3 with a remainder of 388.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2763 away from 3151, we end up with 388.
Fetch the next digit (8) from the dividend, attach it to 388 and continue: 3888 / 921

Step 5:
3888 divided by 921 is 4 with a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 3684 from 3888, we get 204.
Append the next digit (3) from the dividend to 204 and continue with: 2043 / 921

Advancing to step 6:
The number 921 fits into 2043 2 times, leaving a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Subtract 1842 from 2043 to get 201.
Fetch the next digit (3) from the dividend, attach it to 201 and continue: 2013 / 921

Let's proceed to step 7:
When dividing 2013 by 921, we get 2 with a remainder of 171.
Put 2 as the next digit of the answer. 
Result so far: 3422.0
The remainder is 171 after subtracting 1842 from 2013.
Bring next digit (6) of the dividend behind the 171 and repeat the process: 1716 / 921

Step 8:
921 can be fit into 1716 1 times, resulting in a remainder of 795.
Use 1 as the next digit of our solution. 
Result so far: 34221.0
The remainder is 795 after subtracting 921 from 1716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Let's proceed to step 9:
7950 divided by 921 is 8 with a remainder of 582.
The number 8 becomes the next digit in our result. 
Result so far: 34221.8
Deduct 7368 from 7950 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 10:
5820 divided by 921 is 6 with a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 34221.86
If we take 5526 away from 5820, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 11:
When dividing 2940 by 921, we get 3 with a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 34221.863
Deduct 2763 from 2940 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 12:
The number 921 fits into 1770 1 times, leaving a remainder of 849.
Put 1 as the next digit of the answer. 
Result so far: 34221.8631
Deduct 921 from 1770 and we're left with 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

Going ahead to step 13:
The number 921 fits into 8490 9 times, leaving a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 34221.86319
The remainder is 201 after subtracting 8289 from 8490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 14:
2010 divided by 921 is 2 with a remainder of 168.
The next digit of our result is 2. 
Result so far: 34221.863192
If we take 1842 away from 2010, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 15:
If we divide 1680 by 921, we get 1 and a remainder of 759.
Put 1 as the next digit of the answer. 
Result so far: 34221.8631921
If we subtract 921 from 1680, we get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Advancing to step 16:
921 goes into 7590 8 times with a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 34221.86319218
If we subtract 7368 from 7590, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The quotient of the division is 34221.86319218, and the remainder is 2.22e-07.
