43646330 ÷ 959 
Let's see how many times 959 fits into 43646330.

On to step 1:
When dividing 4 by 959, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 959

Moving on to step 2:
When dividing 43 by 959, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 959

Moving on to step 3:
If we divide 436 by 959, we get 0 and a remainder of 436.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 436, we get 436.
Bring next digit (4) of the dividend behind the 436 and repeat the process: 4364 / 959

Let's proceed to step 4:
If we divide 4364 by 959, we get 4 and a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3836 from 4364 and we're left with 528.
Include the next digit (6) from the dividend after 528, then repeat: 5286 / 959

Let's proceed to step 5:
959 can be fit into 5286 5 times, resulting in a remainder of 491.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 4795 from 5286 to get 491.
Take the next digit (3) from the dividend and append it to 491, then repeat: 4913 / 959

On to step 6:
When dividing 4913 by 959, we get 5 with a remainder of 118.
Use 5 as the next digit of our solution. 
Result so far: 455.0
Subtracting 4795 from 4913 leaves us with 118.
Fetch the next digit (3) from the dividend, attach it to 118 and continue: 1183 / 959

Advancing to step 7:
1183 divided by 959 is 1 with a remainder of 224.
The next digit of our result is 1. 
Result so far: 4551.0
The remainder is 224 after subtracting 959 from 1183.
Bring next digit (0) of the dividend behind the 224 and repeat the process: 2240 / 959

On to step 8:
When dividing 2240 by 959, we get 2 with a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 45512.0
The remainder is 322 after subtracting 1918 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 9:
959 goes into 3220 3 times with a remainder of 343.
The next digit of our result is 3. 
Result so far: 45512.3
Subtract 2877 from 3220 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 10:
If we divide 3430 by 959, we get 3 and a remainder of 553.
Write down 3 as next digit of the result. 
Result so far: 45512.33
Subtract 2877 from 3430 to get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

The quotient of the division is 45512.33, and the remainder is 0.553.
