50351193 ÷ 421 
We want to figure out the number of times 50351193 can be divided by 421.

Going ahead to step 1:
The number 421 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 421

Advancing to step 2:
The number 421 fits into 50 0 times, leaving 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.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 421

Let's proceed to step 3:
421 can be fit into 503 1 times, resulting in a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 421 from 503 to get 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 421

Moving on to step 4:
The number 421 fits into 825 1 times, leaving a remainder of 404.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 421 from 825 to get 404.
Append the next digit (1) from the dividend to 404 and continue with: 4041 / 421

Moving on to step 5:
If we divide 4041 by 421, we get 9 and a remainder of 252.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we subtract 3789 from 4041, we get 252.
Append the next digit (1) from the dividend to 252 and continue with: 2521 / 421

Going ahead to step 6:
The number 421 fits into 2521 5 times, leaving a remainder of 416.
Use 5 as the next digit of our solution. 
Result so far: 1195.0
The remainder is 416 after subtracting 2105 from 2521.
Bring next digit (9) of the dividend behind the 416 and repeat the process: 4169 / 421

On to step 7:
The number 421 fits into 4169 9 times, leaving a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 11959.0
Subtracting 3789 from 4169 leaves us with 380.
Fetch the next digit (3) from the dividend, attach it to 380 and continue: 3803 / 421

On to step 8:
421 goes into 3803 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 119599.0
If we subtract 3789 from 3803, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 421, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 119599.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
1400 divided by 421 is 3 with a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 119599.03
Subtracting 1263 from 1400 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 11:
The number 421 fits into 1370 3 times, leaving a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 119599.033
If we subtract 1263 from 1370, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Our division results in 119599.033 with a remaining 0.0107.
