428190 ÷ 63 
We want to figure out the number of times 428190 can be divided by 63.

Advancing to step 1:
When dividing 4 by 63, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 63

On to step 2:
The number 63 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 63

Advancing to step 3:
63 can be fit into 428 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 378 from 428 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 63

On to step 4:
The number 63 fits into 501 7 times, leaving a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we take 441 away from 501, we end up with 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 63

Moving on to step 5:
When dividing 609 by 63, we get 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 679.0
The remainder is 42 after subtracting 567 from 609.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 63

Let's proceed to step 6:
When dividing 420 by 63, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 6796.0
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
63 can be fit into 420 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 6796.6
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
If we divide 420 by 63, we get 6 and a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 6796.66
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 6796.66 with a remainder of 0.042.
