51740795 ÷ 213 
The aim is to understand the frequency of 213 in 51740795.

Moving on to step 1:
213 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 213

Going ahead to step 2:
213 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 213

Let's proceed to step 3:
When dividing 517 by 213, we get 2 with a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 91 after subtracting 426 from 517.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 213

Moving on to step 4:
213 can be fit into 914 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 62 after subtracting 852 from 914.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 213

Going ahead to step 5:
The number 213 fits into 620 2 times, leaving a remainder of 194.
The next digit of our result is 2. 
Result so far: 242.0
Deduct 426 from 620 and we're left with 194.
Include the next digit (7) from the dividend after 194, then repeat: 1947 / 213

Moving on to step 6:
When dividing 1947 by 213, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 2429.0
If we take 1917 away from 1947, we end up with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 213

Let's proceed to step 7:
When dividing 309 by 213, we get 1 with a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 24291.0
Subtracting 213 from 309 leaves us with 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 213

Going ahead to step 8:
If we divide 965 by 213, we get 4 and a remainder of 113.
The next digit of our result is 4. 
Result so far: 242914.0
If we subtract 852 from 965, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
If we divide 1130 by 213, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 242914.5
If we subtract 1065 from 1130, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
213 can be fit into 650 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 242914.53
Subtract 639 from 650 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 213, we get 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 242914.53
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
The number 213 fits into 1100 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 242914.5305
Subtracting 1065 from 1100 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
The number 213 fits into 350 1 times, leaving a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 242914.53051
Subtract 213 from 350 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 14:
213 goes into 1370 6 times with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 242914.530516
If we subtract 1278 from 1370, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
213 can be fit into 920 4 times, resulting in a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 242914.5305164
If we take 852 away from 920, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
The number 213 fits into 680 3 times, leaving a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 242914.53051643
The remainder is 41 after subtracting 639 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 242914.53051643, with a leftover of 4.1e-08.
