We divide 643357 by 63
Let's see how many times 63 fits into 643357.

On to step 1:
The number 63 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 63

Advancing to step 2:
63 can be fit into 64 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 63 from 64 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 63

Advancing to step 3:
63 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 63

On to step 4:
63 can be fit into 133 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 126 away from 133, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 63

Moving on to step 5:
The number 63 fits into 75 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1021.0
Subtract 63 from 75 to get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 63

Advancing to step 6:
63 goes into 127 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 10212.0
If we take 126 away from 127, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
63 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10212.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 63, we get 1 and a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 10212.01
Deduct 63 from 100 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
When dividing 370 by 63, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 10212.015
Subtract 315 from 370 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
When dividing 550 by 63, we get 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 10212.0158
Subtracting 504 from 550 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
63 goes into 460 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 10212.01587
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
The number 63 fits into 190 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 10212.015873
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
63 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10212.015873
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
When dividing 100 by 63, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 10212.01587301
Deduct 63 from 100 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 10212.01587301, with a leftover of 3.7e-08.
