Let's divide 43473586 by 963
We want to figure out the number of times 43473586 can be divided by 963.

Step 1:
The number 963 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.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 963

Step 2:
43 divided by 963 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 963

On to step 3:
The number 963 fits into 434 0 times, leaving a remainder of 434.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Grab the next digit (7) from the dividend, add it to 434, then carry on: 4347 / 963

On to step 4:
When dividing 4347 by 963, we get 4 with a remainder of 495.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3852 from 4347, we get 495.
Bring next digit (3) of the dividend behind the 495 and repeat the process: 4953 / 963

Step 5:
4953 divided by 963 is 5 with a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 4815 from 4953 and we're left with 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 963

Advancing to step 6:
The number 963 fits into 1385 1 times, leaving a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 451.0
Subtracting 963 from 1385 leaves us with 422.
Bring next digit (8) of the dividend behind the 422 and repeat the process: 4228 / 963

Step 7:
4228 divided by 963 is 4 with a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 4514.0
The remainder is 376 after subtracting 3852 from 4228.
Append the next digit (6) from the dividend to 376 and continue with: 3766 / 963

Let's proceed to step 8:
The number 963 fits into 3766 3 times, leaving a remainder of 877.
Use 3 as the next digit of our solution. 
Result so far: 45143.0
The remainder is 877 after subtracting 2889 from 3766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

Advancing to step 9:
If we divide 8770 by 963, we get 9 and a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 45143.9
Subtract 8667 from 8770 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 10:
When dividing 1030 by 963, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 45143.91
If we subtract 963 from 1030, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
963 goes into 670 0 times with a remainder of 670.
Record the quotient 0 as the next digit in the result. 
Result so far: 45143.91
Subtract 0 from 670 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 12:
When dividing 6700 by 963, we get 6 with a remainder of 922.
Use 6 as the next digit of our solution. 
Result so far: 45143.9106
Deduct 5778 from 6700 and we're left with 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Going ahead to step 13:
If we divide 9220 by 963, we get 9 and a remainder of 553.
The number 9 becomes the next digit in our result. 
Result so far: 45143.91069
If we take 8667 away from 9220, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 14:
If we divide 5530 by 963, we get 5 and a remainder of 715.
Put 5 as the next digit of the answer. 
Result so far: 45143.910695
Subtract 4815 from 5530 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Moving on to step 15:
If we divide 7150 by 963, we get 7 and a remainder of 409.
Put 7 as the next digit of the answer. 
Result so far: 45143.9106957
If we subtract 6741 from 7150, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 16:
963 goes into 4090 4 times with a remainder of 238.
The next digit of our result is 4. 
Result so far: 45143.91069574
Subtract 3852 from 4090 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 45143.91069574 and a remainder of 2.38e-07.
