We divide 31367357 by 421
Our goal is to divide 31367357 by 421.

Moving on to step 1:
If we divide 3 by 421, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 421

Let's proceed to step 2:
When dividing 31 by 421, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 421

Step 3:
421 can be fit into 313 0 times, resulting in a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Append the next digit (6) from the dividend to 313 and continue with: 3136 / 421

Moving on to step 4:
When dividing 3136 by 421, we get 7 with a remainder of 189.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2947 from 3136 to get 189.
Bring next digit (7) of the dividend behind the 189 and repeat the process: 1897 / 421

On to step 5:
When dividing 1897 by 421, we get 4 with a remainder of 213.
The next digit of our result is 4. 
Result so far: 74.0
Subtracting 1684 from 1897 leaves us with 213.
Append the next digit (3) from the dividend to 213 and continue with: 2133 / 421

Going ahead to step 6:
If we divide 2133 by 421, we get 5 and a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 745.0
Subtracting 2105 from 2133 leaves us with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 421

Advancing to step 7:
When dividing 285 by 421, we get 0 with a remainder of 285.
Record the quotient 0 as the next digit in the result. 
Result so far: 7450.0
Subtract 0 from 285 to get 285.
Take the next digit (7) from the dividend and append it to 285, then repeat: 2857 / 421

Advancing to step 8:
2857 divided by 421 is 6 with a remainder of 331.
Use 6 as the next digit of our solution. 
Result so far: 74506.0
If we subtract 2526 from 2857, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
3310 divided by 421 is 7 with a remainder of 363.
Write down 7 as next digit of the result. 
Result so far: 74506.7
Subtract 2947 from 3310 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 10:
421 goes into 3630 8 times with a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 74506.78
The remainder is 262 after subtracting 3368 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 11:
If we divide 2620 by 421, we get 6 and a remainder of 94.
The next digit of our result is 6. 
Result so far: 74506.786
If we take 2526 away from 2620, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
421 goes into 940 2 times with a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 74506.7862
If we take 842 away from 940, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 13:
The number 421 fits into 980 2 times, leaving a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 74506.78622
Subtracting 842 from 980 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

After the division, we end up with 74506.78622 and a remainder of 0.000138.
