We divide 43998876 by 850
The aim is to understand the frequency of 850 in 43998876.

Step 1:
850 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 850

Moving on to step 2:
If we divide 43 by 850, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 850

Going ahead to step 3:
850 goes into 439 0 times with a remainder of 439.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 439, we get 439.
Bring next digit (9) of the dividend behind the 439 and repeat the process: 4399 / 850

Going ahead to step 4:
If we divide 4399 by 850, we get 5 and a remainder of 149.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 149 after subtracting 4250 from 4399.
Append the next digit (8) from the dividend to 149 and continue with: 1498 / 850

Step 5:
1498 divided by 850 is 1 with a remainder of 648.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 850 from 1498 leaves us with 648.
Include the next digit (8) from the dividend after 648, then repeat: 6488 / 850

On to step 6:
6488 divided by 850 is 7 with a remainder of 538.
The number 7 becomes the next digit in our result. 
Result so far: 517.0
If we subtract 5950 from 6488, we get 538.
Append the next digit (7) from the dividend to 538 and continue with: 5387 / 850

Going ahead to step 7:
When dividing 5387 by 850, we get 6 with a remainder of 287.
The number 6 becomes the next digit in our result. 
Result so far: 5176.0
Deduct 5100 from 5387 and we're left with 287.
Grab the next digit (6) from the dividend, add it to 287, then carry on: 2876 / 850

Step 8:
850 goes into 2876 3 times with a remainder of 326.
Record the quotient 3 as the next digit in the result. 
Result so far: 51763.0
Subtract 2550 from 2876 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 9:
The number 850 fits into 3260 3 times, leaving a remainder of 710.
The number 3 becomes the next digit in our result. 
Result so far: 51763.3
If we take 2550 away from 3260, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 10:
The number 850 fits into 7100 8 times, leaving a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 51763.38
If we subtract 6800 from 7100, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
3000 divided by 850 is 3 with a remainder of 450.
Record the quotient 3 as the next digit in the result. 
Result so far: 51763.383
Subtract 2550 from 3000 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 12:
If we divide 4500 by 850, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 51763.3835
Deduct 4250 from 4500 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
850 can be fit into 2500 2 times, resulting in a remainder of 800.
Write down 2 as next digit of the result. 
Result so far: 51763.38352
Deduct 1700 from 2500 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 14:
8000 divided by 850 is 9 with a remainder of 350.
Record the quotient 9 as the next digit in the result. 
Result so far: 51763.383529
The remainder is 350 after subtracting 7650 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
When dividing 3500 by 850, we get 4 with a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 51763.3835294
If we subtract 3400 from 3500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
850 can be fit into 1000 1 times, resulting in a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 51763.38352941
Deduct 850 from 1000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 51763.38352941 and a remainder of 1.5e-07.
