38439956 ÷ 454 
We want to divide 38439956 by 454.

Let's proceed to step 1:
When dividing 3 by 454, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 454

Let's proceed to step 2:
454 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 454

Advancing to step 3:
The number 454 fits into 384 0 times, leaving a remainder of 384.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 384 after subtracting 0 from 384.
Append the next digit (3) from the dividend to 384 and continue with: 3843 / 454

Going ahead to step 4:
454 can be fit into 3843 8 times, resulting in a remainder of 211.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 3632 from 3843 to get 211.
Fetch the next digit (9) from the dividend, attach it to 211 and continue: 2119 / 454

Advancing to step 5:
454 can be fit into 2119 4 times, resulting in a remainder of 303.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 1816 from 2119, we get 303.
Bring next digit (9) of the dividend behind the 303 and repeat the process: 3039 / 454

Moving on to step 6:
If we divide 3039 by 454, we get 6 and a remainder of 315.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.0
The remainder is 315 after subtracting 2724 from 3039.
Fetch the next digit (5) from the dividend, attach it to 315 and continue: 3155 / 454

Let's proceed to step 7:
454 can be fit into 3155 6 times, resulting in a remainder of 431.
Record the quotient 6 as the next digit in the result. 
Result so far: 8466.0
If we subtract 2724 from 3155, we get 431.
Include the next digit (6) from the dividend after 431, then repeat: 4316 / 454

Let's proceed to step 8:
454 can be fit into 4316 9 times, resulting in a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 84669.0
If we take 4086 away from 4316, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 9:
The number 454 fits into 2300 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 84669.5
Subtracting 2270 from 2300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 454 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 84669.5
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
454 can be fit into 3000 6 times, resulting in a remainder of 276.
The next digit of our result is 6. 
Result so far: 84669.506
Subtracting 2724 from 3000 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 12:
454 goes into 2760 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 84669.5066
Deduct 2724 from 2760 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 84669.5066 with a remaining 0.00036.
