59592238 ÷ 213 
The aim is to understand the frequency of 213 in 59592238.

Let's proceed to step 1:
If we divide 5 by 213, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 213

On to step 2:
If we divide 59 by 213, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Append the next digit (5) from the dividend to 59 and continue with: 595 / 213

Step 3:
213 can be fit into 595 2 times, resulting in a remainder of 169.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 426 from 595 to get 169.
Bring next digit (9) of the dividend behind the 169 and repeat the process: 1699 / 213

Moving on to step 4:
The number 213 fits into 1699 7 times, leaving a remainder of 208.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 1491 from 1699 leaves us with 208.
Fetch the next digit (2) from the dividend, attach it to 208 and continue: 2082 / 213

Moving on to step 5:
213 goes into 2082 9 times with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
Deduct 1917 from 2082 and we're left with 165.
Fetch the next digit (2) from the dividend, attach it to 165 and continue: 1652 / 213

On to step 6:
When dividing 1652 by 213, we get 7 with a remainder of 161.
The number 7 becomes the next digit in our result. 
Result so far: 2797.0
Subtracting 1491 from 1652 leaves us with 161.
Take the next digit (3) from the dividend and append it to 161, then repeat: 1613 / 213

Going ahead to step 7:
If we divide 1613 by 213, we get 7 and a remainder of 122.
Write down 7 as next digit of the result. 
Result so far: 27977.0
If we subtract 1491 from 1613, we get 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 213

Let's proceed to step 8:
When dividing 1228 by 213, we get 5 with a remainder of 163.
Use 5 as the next digit of our solution. 
Result so far: 279775.0
Subtracting 1065 from 1228 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
When dividing 1630 by 213, we get 7 with a remainder of 139.
Put 7 as the next digit of the answer. 
Result so far: 279775.7
If we take 1491 away from 1630, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
213 can be fit into 1390 6 times, resulting in a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 279775.76
Deduct 1278 from 1390 and we're left with 112.
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:
If we divide 1120 by 213, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 279775.765
Subtracting 1065 from 1120 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
213 goes into 550 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 279775.7652
Subtracting 426 from 550 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 13:
If we divide 1240 by 213, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 279775.76525
Subtract 1065 from 1240 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 14:
If we divide 1750 by 213, we get 8 and a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 279775.765258
Subtracting 1704 from 1750 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 15:
The number 213 fits into 460 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 279775.7652582
Deduct 426 from 460 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 16:
If we divide 340 by 213, we get 1 and a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 279775.76525821
Subtract 213 from 340 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final outcome is 279775.76525821, with a leftover of 1.27e-07.
