39074381 ÷ 214 
The aim is to understand the frequency of 214 in 39074381.

Step 1:
The number 214 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 214

Step 2:
39 divided by 214 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 214

Advancing to step 3:
214 goes into 390 1 times with a remainder of 176.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 214 from 390 and we're left with 176.
Grab the next digit (7) from the dividend, add it to 176, then carry on: 1767 / 214

Moving on to step 4:
When dividing 1767 by 214, we get 8 with a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 1712 from 1767 and we're left with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 214

Moving on to step 5:
554 divided by 214 is 2 with a remainder of 126.
Use 2 as the next digit of our solution. 
Result so far: 182.0
If we subtract 428 from 554, we get 126.
Append the next digit (3) from the dividend to 126 and continue with: 1263 / 214

Moving on to step 6:
The number 214 fits into 1263 5 times, leaving a remainder of 193.
Put 5 as the next digit of the answer. 
Result so far: 1825.0
Subtract 1070 from 1263 to get 193.
Bring next digit (8) of the dividend behind the 193 and repeat the process: 1938 / 214

Going ahead to step 7:
214 can be fit into 1938 9 times, resulting in a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 18259.0
The remainder is 12 after subtracting 1926 from 1938.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 214

Advancing to step 8:
121 divided by 214 is 0 with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 182590.0
Subtracting 0 from 121 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
214 can be fit into 1210 5 times, resulting in a remainder of 140.
The next digit of our result is 5. 
Result so far: 182590.5
The remainder is 140 after subtracting 1070 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 214 fits into 1400 6 times, leaving a remainder of 116.
The next digit of our result is 6. 
Result so far: 182590.56
Deduct 1284 from 1400 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 11:
214 goes into 1160 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 182590.565
Deduct 1070 from 1160 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
900 divided by 214 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 182590.5654
If we take 856 away from 900, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
If we divide 440 by 214, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 182590.56542
If we subtract 428 from 440, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
The number 214 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 182590.56542
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
214 can be fit into 1200 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 182590.5654205
If we take 1070 away from 1200, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
214 can be fit into 1300 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 182590.56542056
Subtract 1284 from 1300 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 182590.56542056, with a leftover of 1.6e-08.
