5311402 ÷ 421 
We want to figure out the number of times 5311402 can be divided by 421.

Advancing to step 1:
421 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 421

On to step 2:
When dividing 53 by 421, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 421

Let's proceed to step 3:
If we divide 531 by 421, we get 1 and a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 421 away from 531, we end up with 110.
Grab the next digit (1) from the dividend, add it to 110, then carry on: 1101 / 421

Advancing to step 4:
421 goes into 1101 2 times with a remainder of 259.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 842 from 1101, we get 259.
Fetch the next digit (4) from the dividend, attach it to 259 and continue: 2594 / 421

On to step 5:
If we divide 2594 by 421, we get 6 and a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 2526 from 2594 to get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 421

Advancing to step 6:
421 goes into 680 1 times with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 1261.0
If we subtract 421 from 680, we get 259.
Include the next digit (2) from the dividend after 259, then repeat: 2592 / 421

Step 7:
When dividing 2592 by 421, we get 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 12616.0
Subtract 2526 from 2592 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
The number 421 fits into 660 1 times, leaving a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 12616.1
Deduct 421 from 660 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
2390 divided by 421 is 5 with a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 12616.15
Subtracting 2105 from 2390 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 10:
421 goes into 2850 6 times with a remainder of 324.
Put 6 as the next digit of the answer. 
Result so far: 12616.156
If we subtract 2526 from 2850, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 11:
421 can be fit into 3240 7 times, resulting in a remainder of 293.
The next digit of our result is 7. 
Result so far: 12616.1567
If we subtract 2947 from 3240, we get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 12:
The number 421 fits into 2930 6 times, leaving a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 12616.15676
Subtracting 2526 from 2930 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 13:
When dividing 4040 by 421, we get 9 with a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 12616.156769
If we take 3789 away from 4040, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 14:
When dividing 2510 by 421, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 12616.1567695
Subtracting 2105 from 2510 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 15:
If we divide 4050 by 421, we get 9 and a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 12616.15676959
If we subtract 3789 from 4050, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 12616.15676959 and a remainder of 2.61e-07.
