We look at the division of 13938936 by 458 
Our goal is to divide 13938936 by 458.

Moving on to step 1:
If we divide 1 by 458, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 458

Step 2:
The number 458 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 458

Advancing to step 3:
The number 458 fits into 139 0 times, leaving a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Take the next digit (3) from the dividend and append it to 139, then repeat: 1393 / 458

Moving on to step 4:
1393 divided by 458 is 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1374 from 1393 leaves us with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 458

Moving on to step 5:
458 can be fit into 198 0 times, resulting in a remainder of 198.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 198 leaves us with 198.
Append the next digit (9) from the dividend to 198 and continue with: 1989 / 458

Let's proceed to step 6:
1989 divided by 458 is 4 with a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 304.0
If we take 1832 away from 1989, we end up with 157.
Bring next digit (3) of the dividend behind the 157 and repeat the process: 1573 / 458

Going ahead to step 7:
If we divide 1573 by 458, we get 3 and a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 3043.0
The remainder is 199 after subtracting 1374 from 1573.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 458

Going ahead to step 8:
When dividing 1996 by 458, we get 4 with a remainder of 164.
Put 4 as the next digit of the answer. 
Result so far: 30434.0
Deduct 1832 from 1996 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 9:
The number 458 fits into 1640 3 times, leaving a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 30434.3
If we take 1374 away from 1640, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 10:
If we divide 2660 by 458, we get 5 and a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 30434.35
Subtract 2290 from 2660 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
458 goes into 3700 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 30434.358
If we subtract 3664 from 3700, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 458, we get 0 and a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 30434.358
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 13:
When dividing 3600 by 458, we get 7 with a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 30434.35807
If we take 3206 away from 3600, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 14:
458 can be fit into 3940 8 times, resulting in a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 30434.358078
Subtract 3664 from 3940 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 15:
458 can be fit into 2760 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 30434.3580786
If we subtract 2748 from 2760, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
The number 458 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 30434.3580786
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 30434.3580786 with a remaining 1.2e-07.
