124888 ÷ 37 
The aim is to understand the frequency of 37 in 124888.

Going ahead to step 1:
The number 37 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 37

On to step 2:
12 divided by 37 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 37

Moving on to step 3:
If we divide 124 by 37, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 111 from 124, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 37

Let's proceed to step 4:
The number 37 fits into 138 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 111 from 138 and we're left with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 37

On to step 5:
When dividing 278 by 37, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 337.0
Deduct 259 from 278 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 37

Going ahead to step 6:
If we divide 198 by 37, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 3375.0
The remainder is 13 after subtracting 185 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
37 can be fit into 130 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3375.3
The remainder is 19 after subtracting 111 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
37 goes into 190 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3375.35
The remainder is 5 after subtracting 185 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
50 divided by 37 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 3375.351
If we take 37 away from 50, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
If we divide 130 by 37, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 3375.3513
Subtracting 111 from 130 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
190 divided by 37 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3375.35135
Subtract 185 from 190 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 37, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 3375.351351
Deduct 37 from 50 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
The number 37 fits into 130 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3375.3513513
Deduct 111 from 130 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
190 divided by 37 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3375.35135135
If we subtract 185 from 190, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 3375.35135135 and a remainder of 5e-09.
