29863874 ÷ 850 
The aim is to understand the frequency of 850 in 29863874.

Step 1:
When dividing 2 by 850, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 850

Going ahead to step 2:
When dividing 29 by 850, we get 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 850

Moving on to step 3:
If we divide 298 by 850, we get 0 and a remainder of 298.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 298 to get 298.
Fetch the next digit (6) from the dividend, attach it to 298 and continue: 2986 / 850

Advancing to step 4:
2986 divided by 850 is 3 with a remainder of 436.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2550 from 2986 and we're left with 436.
Take the next digit (3) from the dividend and append it to 436, then repeat: 4363 / 850

Advancing to step 5:
If we divide 4363 by 850, we get 5 and a remainder of 113.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 4250 from 4363, we get 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 850

Advancing to step 6:
1138 divided by 850 is 1 with a remainder of 288.
The next digit of our result is 1. 
Result so far: 351.0
Deduct 850 from 1138 and we're left with 288.
Grab the next digit (7) from the dividend, add it to 288, then carry on: 2887 / 850

On to step 7:
When dividing 2887 by 850, we get 3 with a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 3513.0
Deduct 2550 from 2887 and we're left with 337.
Append the next digit (4) from the dividend to 337 and continue with: 3374 / 850

Going ahead to step 8:
850 can be fit into 3374 3 times, resulting in a remainder of 824.
Record the quotient 3 as the next digit in the result. 
Result so far: 35133.0
The remainder is 824 after subtracting 2550 from 3374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Moving on to step 9:
850 can be fit into 8240 9 times, resulting in a remainder of 590.
Record the quotient 9 as the next digit in the result. 
Result so far: 35133.9
If we subtract 7650 from 8240, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 10:
The number 850 fits into 5900 6 times, leaving a remainder of 800.
Use 6 as the next digit of our solution. 
Result so far: 35133.96
If we subtract 5100 from 5900, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 11:
When dividing 8000 by 850, we get 9 with a remainder of 350.
Put 9 as the next digit of the answer. 
Result so far: 35133.969
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 12:
The number 850 fits into 3500 4 times, leaving a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 35133.9694
Subtracting 3400 from 3500 leaves us with 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 13:
850 goes into 1000 1 times with a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 35133.96941
Subtracting 850 from 1000 leaves us 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.

Advancing to step 14:
850 can be fit into 1500 1 times, resulting in a remainder of 650.
Use 1 as the next digit of our solution. 
Result so far: 35133.969411
Deduct 850 from 1500 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final result is 35133.969411 with a remainder of 6.5e-05.
