We look at the division of 43237128 by 408 
Let's see how many times 408 fits into 43237128.

Advancing to step 1:
The number 408 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 408

Step 2:
408 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 408

Let's proceed to step 3:
The number 408 fits into 432 1 times, leaving a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 408 from 432 and we're left with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 408

Going ahead to step 4:
408 can be fit into 243 0 times, resulting in a remainder of 243.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 243, we get 243.
Include the next digit (7) from the dividend after 243, then repeat: 2437 / 408

On to step 5:
2437 divided by 408 is 5 with a remainder of 397.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Deduct 2040 from 2437 and we're left with 397.
Bring next digit (1) of the dividend behind the 397 and repeat the process: 3971 / 408

Advancing to step 6:
If we divide 3971 by 408, we get 9 and a remainder of 299.
The next digit of our result is 9. 
Result so far: 1059.0
If we subtract 3672 from 3971, we get 299.
Include the next digit (2) from the dividend after 299, then repeat: 2992 / 408

Step 7:
2992 divided by 408 is 7 with a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 10597.0
If we subtract 2856 from 2992, we get 136.
Include the next digit (8) from the dividend after 136, then repeat: 1368 / 408

Moving on to step 8:
1368 divided by 408 is 3 with a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 105973.0
Subtracting 1224 from 1368 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
408 can be fit into 1440 3 times, resulting in a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 105973.3
If we subtract 1224 from 1440, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 10:
2160 divided by 408 is 5 with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 105973.35
Subtracting 2040 from 2160 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
408 goes into 1200 2 times with a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 105973.352
The remainder is 384 after subtracting 816 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 12:
408 goes into 3840 9 times with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 105973.3529
If we take 3672 away from 3840, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 13:
408 can be fit into 1680 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 105973.35294
Subtract 1632 from 1680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
When dividing 480 by 408, we get 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 105973.352941
If we take 408 away from 480, 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.

On to step 15:
The number 408 fits into 720 1 times, leaving a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 105973.3529411
If we subtract 408 from 720, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 105973.3529411 with a remaining 3.12e-06.
