Let's divide 90398943 by 63
We want to figure out the number of times 90398943 can be divided by 63.

Step 1:
9 divided by 63 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 63

On to step 2:
The number 63 fits into 90 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 63 from 90 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 63

On to step 3:
63 goes into 273 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 252 from 273 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 63

Advancing to step 4:
If we divide 219 by 63, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
Subtracting 189 from 219 leaves us with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 63

Advancing to step 5:
63 can be fit into 308 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 1434.0
If we subtract 252 from 308, we get 56.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 63

Advancing to step 6:
63 can be fit into 569 9 times, resulting in a remainder of 2.
The next digit of our result is 9. 
Result so far: 14349.0
Deduct 567 from 569 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 63

Step 7:
The number 63 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 143490.0
If we subtract 0 from 24, we get 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 63

Advancing to step 8:
63 can be fit into 243 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 1434903.0
The remainder is 54 after subtracting 189 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
63 goes into 540 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 1434903.8
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1434903.85
Subtract 315 from 360 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
The number 63 fits into 450 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1434903.857
Subtracting 441 from 450 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
If we divide 90 by 63, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1434903.8571
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
The number 63 fits into 270 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 1434903.85714
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
If we divide 180 by 63, we get 2 and a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 1434903.857142
Deduct 126 from 180 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 15:
If we divide 540 by 63, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 1434903.8571428
Subtracting 504 from 540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 16:
63 goes into 360 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1434903.85714285
Subtracting 315 from 360 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 1434903.85714285 with a remainder of 4.5e-08.
