38891993 divided by 451 
We want to divide 38891993 by 451.

Advancing to step 1:
If we divide 3 by 451, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 451

Step 2:
451 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 451

Advancing to step 3:
If we divide 388 by 451, we get 0 and a remainder of 388.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 388 after subtracting 0 from 388.
Take the next digit (9) from the dividend and append it to 388, then repeat: 3889 / 451

Advancing to step 4:
451 goes into 3889 8 times with a remainder of 281.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 3608 from 3889, we get 281.
Append the next digit (1) from the dividend to 281 and continue with: 2811 / 451

Advancing to step 5:
2811 divided by 451 is 6 with a remainder of 105.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 2706 from 2811 and we're left with 105.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 451

Moving on to step 6:
The number 451 fits into 1059 2 times, leaving a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
If we take 902 away from 1059, we end up with 157.
Append the next digit (9) from the dividend to 157 and continue with: 1579 / 451

Step 7:
When dividing 1579 by 451, we get 3 with a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 8623.0
Deduct 1353 from 1579 and we're left with 226.
Take the next digit (3) from the dividend and append it to 226, then repeat: 2263 / 451

On to step 8:
2263 divided by 451 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 86235.0
The remainder is 8 after subtracting 2255 from 2263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 451 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 86235.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
The number 451 fits into 800 1 times, leaving a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 86235.01
Subtract 451 from 800 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 11:
If we divide 3490 by 451, we get 7 and a remainder of 333.
Use 7 as the next digit of our solution. 
Result so far: 86235.017
If we take 3157 away from 3490, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 12:
451 goes into 3330 7 times with a remainder of 173.
The next digit of our result is 7. 
Result so far: 86235.0177
Subtracting 3157 from 3330 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

In conclusion, the division gives 86235.0177 with a balance of 0.00173.
