38251784 divided by 124 
The aim is to understand the frequency of 124 in 38251784.

Going ahead to step 1:
If we divide 3 by 124, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 124

Step 2:
The number 124 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 124

Going ahead to step 3:
382 divided by 124 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 372 from 382 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 124

Advancing to step 4:
The number 124 fits into 105 0 times, leaving a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 105, we end up with 105.
Fetch the next digit (1) from the dividend, attach it to 105 and continue: 1051 / 124

Step 5:
1051 divided by 124 is 8 with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
Deduct 992 from 1051 and we're left with 59.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 124

Advancing to step 6:
597 divided by 124 is 4 with a remainder of 101.
Put 4 as the next digit of the answer. 
Result so far: 3084.0
If we subtract 496 from 597, we get 101.
Bring next digit (8) of the dividend behind the 101 and repeat the process: 1018 / 124

Let's proceed to step 7:
If we divide 1018 by 124, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 30848.0
If we take 992 away from 1018, we end up with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 124

Advancing to step 8:
When dividing 264 by 124, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 308482.0
Deduct 248 from 264 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 124, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 308482.1
If we subtract 124 from 160, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
If we divide 360 by 124, we get 2 and a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 308482.12
Deduct 248 from 360 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.

Step 11:
1120 divided by 124 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 308482.129
Subtracting 1116 from 1120 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
124 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 308482.129
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
The number 124 fits into 400 3 times, leaving a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 308482.12903
The remainder is 28 after subtracting 372 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
If we divide 280 by 124, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 308482.129032
The remainder is 32 after subtracting 248 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
124 goes into 320 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 308482.1290322
Subtracting 248 from 320 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 308482.1290322 with a remaining 7.2e-07.
