Let's divide 37390451 by 238
The aim is to understand the frequency of 238 in 37390451.

Moving on to step 1:
3 divided by 238 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 238

Going ahead to step 2:
If we divide 37 by 238, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 238

Advancing to step 3:
If we divide 373 by 238, we get 1 and a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 238 from 373 leaves us with 135.
Fetch the next digit (9) from the dividend, attach it to 135 and continue: 1359 / 238

Advancing to step 4:
238 can be fit into 1359 5 times, resulting in a remainder of 169.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 169 after subtracting 1190 from 1359.
Append the next digit (0) from the dividend to 169 and continue with: 1690 / 238

Advancing to step 5:
If we divide 1690 by 238, we get 7 and a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 1666 from 1690 to get 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 238

Step 6:
238 can be fit into 244 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 1571.0
Deduct 238 from 244 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 238

Advancing to step 7:
65 divided by 238 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 15710.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 238

Moving on to step 8:
When dividing 651 by 238, we get 2 with a remainder of 175.
Put 2 as the next digit of the answer. 
Result so far: 157102.0
Subtracting 476 from 651 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
When dividing 1750 by 238, we get 7 with a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 157102.7
The remainder is 84 after subtracting 1666 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
238 goes into 840 3 times with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 157102.73
Subtracting 714 from 840 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 11:
238 can be fit into 1260 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 157102.735
Subtracting 1190 from 1260 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
238 goes into 700 2 times with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 157102.7352
Subtract 476 from 700 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 13:
238 can be fit into 2240 9 times, resulting in a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 157102.73529
If we take 2142 away from 2240, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 14:
If we divide 980 by 238, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 157102.735294
Subtracting 952 from 980 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
The number 238 fits into 280 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 157102.7352941
Deduct 238 from 280 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 16:
238 can be fit into 420 1 times, resulting in a remainder of 182.
Write down 1 as next digit of the result. 
Result so far: 157102.73529411
Subtracting 238 from 420 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 157102.73529411 and a remainder of 1.82e-07.
