We're dividing 63628535 by 438 
Our goal is to divide 63628535 by 438.

Step 1:
The number 438 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 438

Let's proceed to step 2:
If we divide 63 by 438, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 438

Advancing to step 3:
If we divide 636 by 438, we get 1 and a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 438 from 636 to get 198.
Fetch the next digit (2) from the dividend, attach it to 198 and continue: 1982 / 438

Let's proceed to step 4:
1982 divided by 438 is 4 with a remainder of 230.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1752 from 1982 and we're left with 230.
Append the next digit (8) from the dividend to 230 and continue with: 2308 / 438

Let's proceed to step 5:
If we divide 2308 by 438, we get 5 and a remainder of 118.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we subtract 2190 from 2308, we get 118.
Include the next digit (5) from the dividend after 118, then repeat: 1185 / 438

Step 6:
The number 438 fits into 1185 2 times, leaving a remainder of 309.
Put 2 as the next digit of the answer. 
Result so far: 1452.0
Subtract 876 from 1185 to get 309.
Append the next digit (3) from the dividend to 309 and continue with: 3093 / 438

On to step 7:
3093 divided by 438 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 14527.0
If we take 3066 away from 3093, we end up with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 438

Advancing to step 8:
If we divide 275 by 438, we get 0 and a remainder of 275.
The number 0 becomes the next digit in our result. 
Result so far: 145270.0
Deduct 0 from 275 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 9:
The number 438 fits into 2750 6 times, leaving a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 145270.6
If we subtract 2628 from 2750, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
If we divide 1220 by 438, we get 2 and a remainder of 344.
Write down 2 as next digit of the result. 
Result so far: 145270.62
Subtracting 876 from 1220 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
438 goes into 3440 7 times with a remainder of 374.
Put 7 as the next digit of the answer. 
Result so far: 145270.627
If we take 3066 away from 3440, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 12:
When dividing 3740 by 438, we get 8 with a remainder of 236.
The next digit of our result is 8. 
Result so far: 145270.6278
The remainder is 236 after subtracting 3504 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 13:
If we divide 2360 by 438, we get 5 and a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 145270.62785
Deduct 2190 from 2360 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 14:
438 can be fit into 1700 3 times, resulting in a remainder of 386.
Put 3 as the next digit of the answer. 
Result so far: 145270.627853
Subtracting 1314 from 1700 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 15:
The number 438 fits into 3860 8 times, leaving a remainder of 356.
The next digit of our result is 8. 
Result so far: 145270.6278538
Deduct 3504 from 3860 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 16:
When dividing 3560 by 438, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 145270.62785388
If we subtract 3504 from 3560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 145270.62785388 and a remainder of 5.6e-08.
