We look at the division of 37929423 by 868 
The aim is to understand the frequency of 868 in 37929423.

Step 1:
868 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 868

On to step 2:
If we divide 37 by 868, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 868

Going ahead to step 3:
868 can be fit into 379 0 times, resulting in a remainder of 379.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 379 and we're left with 379.
Fetch the next digit (2) from the dividend, attach it to 379 and continue: 3792 / 868

Step 4:
The number 868 fits into 3792 4 times, leaving a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 320 after subtracting 3472 from 3792.
Include the next digit (9) from the dividend after 320, then repeat: 3209 / 868

Moving on to step 5:
When dividing 3209 by 868, we get 3 with a remainder of 605.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 605 after subtracting 2604 from 3209.
Fetch the next digit (4) from the dividend, attach it to 605 and continue: 6054 / 868

On to step 6:
868 goes into 6054 6 times with a remainder of 846.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we subtract 5208 from 6054, we get 846.
Include the next digit (2) from the dividend after 846, then repeat: 8462 / 868

On to step 7:
When dividing 8462 by 868, we get 9 with a remainder of 650.
The number 9 becomes the next digit in our result. 
Result so far: 4369.0
The remainder is 650 after subtracting 7812 from 8462.
Fetch the next digit (3) from the dividend, attach it to 650 and continue: 6503 / 868

Advancing to step 8:
When dividing 6503 by 868, we get 7 with a remainder of 427.
The next digit of our result is 7. 
Result so far: 43697.0
If we take 6076 away from 6503, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Moving on to step 9:
4270 divided by 868 is 4 with a remainder of 798.
Put 4 as the next digit of the answer. 
Result so far: 43697.4
If we subtract 3472 from 4270, we get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

On to step 10:
When dividing 7980 by 868, we get 9 with a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 43697.49
Subtract 7812 from 7980 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 11:
1680 divided by 868 is 1 with a remainder of 812.
Record the quotient 1 as the next digit in the result. 
Result so far: 43697.491
Subtracting 868 from 1680 leaves us with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Let's proceed to step 12:
The number 868 fits into 8120 9 times, leaving a remainder of 308.
Record the quotient 9 as the next digit in the result. 
Result so far: 43697.4919
Subtract 7812 from 8120 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 13:
868 goes into 3080 3 times with a remainder of 476.
Record the quotient 3 as the next digit in the result. 
Result so far: 43697.49193
Subtract 2604 from 3080 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 14:
868 can be fit into 4760 5 times, resulting in a remainder of 420.
Record the quotient 5 as the next digit in the result. 
Result so far: 43697.491935
Subtracting 4340 from 4760 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 15:
If we divide 4200 by 868, we get 4 and a remainder of 728.
Put 4 as the next digit of the answer. 
Result so far: 43697.4919354
Subtracting 3472 from 4200 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 16:
When dividing 7280 by 868, we get 8 with a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 43697.49193548
Subtracting 6944 from 7280 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 43697.49193548 with a remainder of 3.36e-07.
