42020217 divided by 850 
The aim is to understand the frequency of 850 in 42020217.

Advancing to step 1:
850 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 850

Moving on to step 2:
When dividing 42 by 850, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 850

On to step 3:
If we divide 420 by 850, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Take the next digit (2) from the dividend and append it to 420, then repeat: 4202 / 850

Going ahead to step 4:
If we divide 4202 by 850, we get 4 and a remainder of 802.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 802 after subtracting 3400 from 4202.
Append the next digit (0) from the dividend to 802 and continue with: 8020 / 850

Going ahead to step 5:
8020 divided by 850 is 9 with a remainder of 370.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 7650 from 8020 leaves us with 370.
Take the next digit (2) from the dividend and append it to 370, then repeat: 3702 / 850

Going ahead to step 6:
850 goes into 3702 4 times with a remainder of 302.
Use 4 as the next digit of our solution. 
Result so far: 494.0
The remainder is 302 after subtracting 3400 from 3702.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 850

Moving on to step 7:
If we divide 3021 by 850, we get 3 and a remainder of 471.
Use 3 as the next digit of our solution. 
Result so far: 4943.0
Deduct 2550 from 3021 and we're left with 471.
Fetch the next digit (7) from the dividend, attach it to 471 and continue: 4717 / 850

Step 8:
The number 850 fits into 4717 5 times, leaving a remainder of 467.
The next digit of our result is 5. 
Result so far: 49435.0
Deduct 4250 from 4717 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 9:
When dividing 4670 by 850, we get 5 with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 49435.5
If we take 4250 away from 4670, we end up 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.

Going ahead to step 10:
850 can be fit into 4200 4 times, resulting in a remainder of 800.
The number 4 becomes the next digit in our result. 
Result so far: 49435.54
The remainder is 800 after subtracting 3400 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 11:
850 goes into 8000 9 times with a remainder of 350.
Write down 9 as next digit of the result. 
Result so far: 49435.549
Subtracting 7650 from 8000 leaves us with 350.
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:
850 can be fit into 3500 4 times, resulting in a remainder of 100.
The next digit of our result is 4. 
Result so far: 49435.5494
The remainder is 100 after subtracting 3400 from 3500.
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:
If we divide 1000 by 850, we get 1 and a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 49435.54941
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: 49435.549411
The remainder is 650 after subtracting 850 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Our division results in 49435.549411 with a remaining 6.5e-05.
