Put 4 as the next digit of the answer. 
Result so far: 1944.0
Subtracting 3620 from 3624 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 905

Let's proceed to step 8:
If we divide 43 by 905, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 19440.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
If we divide 430 by 905, we get 0 and a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 19440.0
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
905 goes into 4300 4 times with a remainder of 680.
Use 4 as the next digit of our solution. 
Result so far: 19440.04
Subtract 3620 from 4300 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 11:
When dividing 6800 by 905, we get 7 with a remainder of 465.
Use 7 as the next digit of our solution. 
Result so far: 19440.047
Subtracting 6335 from 6800 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 12:
The number 905 fits into 4650 5 times, leaving a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 19440.0475
Deduct 4525 from 4650 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 13:
1250 divided by 905 is 1 with a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 19440.04751
Deduct 905 from 1250 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 14:
905 can be fit into 3450 3 times, resulting in a remainder of 735.
The number 3 becomes the next digit in our result. 
Result so far: 19440.047513
If we take 2715 away from 3450, we end up with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Step 15:
905 can be fit into 7350 8 times, resulting in a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 19440.0475138
If we subtract 7240 from 7350, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
The number 905 fits into 1100 1 times, leaving a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 19440.04751381
Deduct 905 from 1100 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.
