We're dividing 85517072 by 438 
Let's see how many times 438 fits into 85517072.

Moving on to step 1:
The number 438 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 438

Going ahead to step 2:
If we divide 85 by 438, we get 0 and a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 438

Moving on to step 3:
If we divide 855 by 438, we get 1 and a remainder of 417.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 438 from 855, we get 417.
Grab the next digit (1) from the dividend, add it to 417, then carry on: 4171 / 438

Going ahead to step 4:
4171 divided by 438 is 9 with a remainder of 229.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 3942 from 4171 to get 229.
Take the next digit (7) from the dividend and append it to 229, then repeat: 2297 / 438

Step 5:
When dividing 2297 by 438, we get 5 with a remainder of 107.
The next digit of our result is 5. 
Result so far: 195.0
If we subtract 2190 from 2297, we get 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 438

Advancing to step 6:
1070 divided by 438 is 2 with a remainder of 194.
The next digit of our result is 2. 
Result so far: 1952.0
Deduct 876 from 1070 and we're left with 194.
Take the next digit (7) from the dividend and append it to 194, then repeat: 1947 / 438

Advancing to step 7:
1947 divided by 438 is 4 with a remainder of 195.
Record the quotient 4 as the next digit in the result. 
Result so far: 19524.0
Deduct 1752 from 1947 and we're left with 195.
Include the next digit (2) from the dividend after 195, then repeat: 1952 / 438

Step 8:
438 can be fit into 1952 4 times, resulting in a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 195244.0
If we subtract 1752 from 1952, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 9:
The number 438 fits into 2000 4 times, leaving a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 195244.4
The remainder is 248 after subtracting 1752 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 10:
438 can be fit into 2480 5 times, resulting in a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 195244.45
Subtracting 2190 from 2480 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 11:
If we divide 2900 by 438, we get 6 and a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 195244.456
If we take 2628 away from 2900, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 12:
2720 divided by 438 is 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 195244.4566
Subtracting 2628 from 2720 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

After the division, we end up with 195244.4566 and a remainder of 0.00092.
