72510677 ÷ 213 
The aim is to understand the frequency of 213 in 72510677.

Going ahead to step 1:
213 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 213

On to step 2:
The number 213 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 213

Let's proceed to step 3:
213 goes into 725 3 times with a remainder of 86.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 639 from 725 leaves us with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 213

On to step 4:
If we divide 861 by 213, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 852 from 861, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 213

Step 5:
If we divide 90 by 213, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 340.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 213

Moving on to step 6:
213 goes into 906 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 3404.0
If we subtract 852 from 906, we get 54.
Fetch the next digit (7) from the dividend, attach it to 54 and continue: 547 / 213

Going ahead to step 7:
If we divide 547 by 213, we get 2 and a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 34042.0
If we subtract 426 from 547, we get 121.
Take the next digit (7) from the dividend and append it to 121, then repeat: 1217 / 213

Let's proceed to step 8:
1217 divided by 213 is 5 with a remainder of 152.
Put 5 as the next digit of the answer. 
Result so far: 340425.0
Subtract 1065 from 1217 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 9:
If we divide 1520 by 213, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 340425.7
If we take 1491 away from 1520, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
The number 213 fits into 290 1 times, leaving a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 340425.71
Deduct 213 from 290 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
The number 213 fits into 770 3 times, leaving a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 340425.713
If we subtract 639 from 770, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 12:
1310 divided by 213 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 340425.7136
The remainder is 32 after subtracting 1278 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
320 divided by 213 is 1 with a remainder of 107.
Put 1 as the next digit of the answer. 
Result so far: 340425.71361
If we subtract 213 from 320, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 14:
1070 divided by 213 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 340425.713615
The remainder is 5 after subtracting 1065 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 15:
50 divided by 213 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 340425.713615
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
If we divide 500 by 213, we get 2 and a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 340425.71361502
If we take 426 away from 500, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 340425.71361502 and a remainder of 7.4e-08.
