We're dividing 50289867 by 420 
Let's see how many times 420 fits into 50289867.

Advancing to step 1:
When dividing 5 by 420, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 420

On to step 2:
If we divide 50 by 420, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 420

On to step 3:
When dividing 502 by 420, we get 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 420 from 502 leaves us with 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 420

On to step 4:
The number 420 fits into 828 1 times, leaving a remainder of 408.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 420 from 828, we get 408.
Bring next digit (9) of the dividend behind the 408 and repeat the process: 4089 / 420

On to step 5:
The number 420 fits into 4089 9 times, leaving a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 3780 from 4089 and we're left with 309.
Bring next digit (8) of the dividend behind the 309 and repeat the process: 3098 / 420

Advancing to step 6:
If we divide 3098 by 420, we get 7 and a remainder of 158.
Write down 7 as next digit of the result. 
Result so far: 1197.0
Subtract 2940 from 3098 to get 158.
Bring next digit (6) of the dividend behind the 158 and repeat the process: 1586 / 420

Going ahead to step 7:
The number 420 fits into 1586 3 times, leaving a remainder of 326.
The number 3 becomes the next digit in our result. 
Result so far: 11973.0
Subtract 1260 from 1586 to get 326.
Take the next digit (7) from the dividend and append it to 326, then repeat: 3267 / 420

On to step 8:
If we divide 3267 by 420, we get 7 and a remainder of 327.
Use 7 as the next digit of our solution. 
Result so far: 119737.0
Deduct 2940 from 3267 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 9:
420 can be fit into 3270 7 times, resulting in a remainder of 330.
Record the quotient 7 as the next digit in the result. 
Result so far: 119737.7
If we subtract 2940 from 3270, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
When dividing 3300 by 420, we get 7 with a remainder of 360.
Put 7 as the next digit of the answer. 
Result so far: 119737.77
Subtracting 2940 from 3300 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 119737.77 and a remainder of 0.36.
