Let's divide 67370145 by 221
The aim is to understand the frequency of 221 in 67370145.

Step 1:
6 divided by 221 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 221

Let's proceed to step 2:
221 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 221

Step 3:
221 goes into 673 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 663 from 673 to get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 221

Step 4:
221 can be fit into 107 0 times, resulting in a remainder of 107.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 107, we end up with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 221

Step 5:
When dividing 1070 by 221, we get 4 with a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 304.0
The remainder is 186 after subtracting 884 from 1070.
Take the next digit (1) from the dividend and append it to 186, then repeat: 1861 / 221

Going ahead to step 6:
221 can be fit into 1861 8 times, resulting in a remainder of 93.
Put 8 as the next digit of the answer. 
Result so far: 3048.0
Subtracting 1768 from 1861 leaves us with 93.
Take the next digit (4) from the dividend and append it to 93, then repeat: 934 / 221

Advancing to step 7:
221 goes into 934 4 times with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 30484.0
Subtract 884 from 934 to get 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 221

Advancing to step 8:
221 goes into 505 2 times with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 304842.0
Subtracting 442 from 505 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
221 can be fit into 630 2 times, resulting in a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 304842.2
Subtract 442 from 630 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
1880 divided by 221 is 8 with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 304842.28
The remainder is 112 after subtracting 1768 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
When dividing 1120 by 221, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 304842.285
The remainder is 15 after subtracting 1105 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 221 is 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 304842.285
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
When dividing 1500 by 221, we get 6 with a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 304842.28506
If we take 1326 away from 1500, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 14:
221 goes into 1740 7 times with a remainder of 193.
The number 7 becomes the next digit in our result. 
Result so far: 304842.285067
Subtract 1547 from 1740 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 15:
The number 221 fits into 1930 8 times, leaving a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 304842.2850678
If we take 1768 away from 1930, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 16:
When dividing 1620 by 221, we get 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 304842.28506787
Deduct 1547 from 1620 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

After the division, we end up with 304842.28506787 and a remainder of 7.3e-08.
