We're dividing 43203463 by 137 
Our goal is to divide 43203463 by 137.

Moving on to step 1:
137 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 137

On to step 2:
43 divided by 137 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 137

Advancing to step 3:
The number 137 fits into 432 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 411 from 432 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 137

Going ahead to step 4:
137 can be fit into 210 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 137 from 210 to get 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 137

Let's proceed to step 5:
137 can be fit into 733 5 times, resulting in a remainder of 48.
The next digit of our result is 5. 
Result so far: 315.0
If we take 685 away from 733, we end up with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 137

Going ahead to step 6:
When dividing 484 by 137, we get 3 with a remainder of 73.
The next digit of our result is 3. 
Result so far: 3153.0
Subtracting 411 from 484 leaves us with 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 137

Step 7:
When dividing 736 by 137, we get 5 with a remainder of 51.
The next digit of our result is 5. 
Result so far: 31535.0
Deduct 685 from 736 and we're left with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 137

Going ahead to step 8:
513 divided by 137 is 3 with a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 315353.0
Deduct 411 from 513 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 9:
If we divide 1020 by 137, we get 7 and a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 315353.7
Deduct 959 from 1020 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
137 goes into 610 4 times with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 315353.74
If we take 548 away from 610, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
The number 137 fits into 620 4 times, leaving a remainder of 72.
The next digit of our result is 4. 
Result so far: 315353.744
If we take 548 away from 620, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 315353.744 and a remainder of 0.0072.
