We're dividing 20085529 by 438 
We're looking to find how many times 438 goes into 20085529.

Step 1:
When dividing 2 by 438, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 438

Advancing to step 2:
438 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 438

Going ahead to step 3:
When dividing 200 by 438, we get 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 200 and we're left with 200.
Take the next digit (8) from the dividend and append it to 200, then repeat: 2008 / 438

Moving on to step 4:
When dividing 2008 by 438, we get 4 with a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1752 from 2008, we get 256.
Fetch the next digit (5) from the dividend, attach it to 256 and continue: 2565 / 438

Advancing to step 5:
2565 divided by 438 is 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 2190 away from 2565, we end up with 375.
Include the next digit (5) from the dividend after 375, then repeat: 3755 / 438

Let's proceed to step 6:
438 can be fit into 3755 8 times, resulting in a remainder of 251.
Record the quotient 8 as the next digit in the result. 
Result so far: 458.0
Deduct 3504 from 3755 and we're left with 251.
Fetch the next digit (2) from the dividend, attach it to 251 and continue: 2512 / 438

Going ahead to step 7:
438 can be fit into 2512 5 times, resulting in a remainder of 322.
The number 5 becomes the next digit in our result. 
Result so far: 4585.0
The remainder is 322 after subtracting 2190 from 2512.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 438

Advancing to step 8:
If we divide 3229 by 438, we get 7 and a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 45857.0
Subtract 3066 from 3229 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
The number 438 fits into 1630 3 times, leaving a remainder of 316.
Record the quotient 3 as the next digit in the result. 
Result so far: 45857.3
Subtracting 1314 from 1630 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 10:
438 can be fit into 3160 7 times, resulting in a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 45857.37
If we take 3066 away from 3160, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
940 divided by 438 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 45857.372
If we subtract 876 from 940, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
When dividing 640 by 438, we get 1 with a remainder of 202.
The next digit of our result is 1. 
Result so far: 45857.3721
Subtract 438 from 640 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 13:
2020 divided by 438 is 4 with a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 45857.37214
If we take 1752 away from 2020, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 14:
If we divide 2680 by 438, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 45857.372146
Subtract 2628 from 2680 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 15:
438 can be fit into 520 1 times, resulting in a remainder of 82.
The next digit of our result is 1. 
Result so far: 45857.3721461
Subtract 438 from 520 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 16:
438 goes into 820 1 times with a remainder of 382.
The next digit of our result is 1. 
Result so far: 45857.37214611
Subtracting 438 from 820 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

The final result is 45857.37214611 with a remainder of 3.82e-07.
