7638429 ÷ 223 
Let's see how many times 223 fits into 7638429.

Moving on to step 1:
223 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 223

Moving on to step 2:
223 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 223

Step 3:
If we divide 763 by 223, we get 3 and a remainder of 94.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 669 from 763 to get 94.
Append the next digit (8) from the dividend to 94 and continue with: 948 / 223

Let's proceed to step 4:
223 can be fit into 948 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 892 from 948 leaves us with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 223

Advancing to step 5:
The number 223 fits into 564 2 times, leaving a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 342.0
The remainder is 118 after subtracting 446 from 564.
Fetch the next digit (2) from the dividend, attach it to 118 and continue: 1182 / 223

Let's proceed to step 6:
223 can be fit into 1182 5 times, resulting in a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 3425.0
If we take 1115 away from 1182, we end up with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 223

Step 7:
When dividing 679 by 223, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 34253.0
Subtract 669 from 679 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
223 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 34253.0
Subtract 0 from 100 to get 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 9:
1000 divided by 223 is 4 with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 34253.04
Subtracting 892 from 1000 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
If we divide 1080 by 223, we get 4 and a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 34253.044
The remainder is 188 after subtracting 892 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Our division results in 34253.044 with a remaining 0.0188.
