38729633 ÷ 857 
Our goal is to divide 38729633 by 857.

Step 1:
When dividing 3 by 857, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 857

On to step 2:
857 can be fit into 38 0 times, resulting in a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 857

Step 3:
857 can be fit into 387 0 times, resulting in a remainder of 387.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 387 and we're left with 387.
Take the next digit (2) from the dividend and append it to 387, then repeat: 3872 / 857

Let's proceed to step 4:
When dividing 3872 by 857, we get 4 with a remainder of 444.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3428 from 3872 leaves us with 444.
Bring next digit (9) of the dividend behind the 444 and repeat the process: 4449 / 857

On to step 5:
The number 857 fits into 4449 5 times, leaving a remainder of 164.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 4285 away from 4449, we end up with 164.
Include the next digit (6) from the dividend after 164, then repeat: 1646 / 857

Moving on to step 6:
If we divide 1646 by 857, we get 1 and a remainder of 789.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
The remainder is 789 after subtracting 857 from 1646.
Bring next digit (3) of the dividend behind the 789 and repeat the process: 7893 / 857

On to step 7:
If we divide 7893 by 857, we get 9 and a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 4519.0
Subtracting 7713 from 7893 leaves us with 180.
Bring next digit (3) of the dividend behind the 180 and repeat the process: 1803 / 857

On to step 8:
1803 divided by 857 is 2 with a remainder of 89.
Use 2 as the next digit of our solution. 
Result so far: 45192.0
Subtracting 1714 from 1803 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 9:
The number 857 fits into 890 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 45192.1
If we subtract 857 from 890, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
857 goes into 330 0 times with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 45192.1
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 11:
If we divide 3300 by 857, we get 3 and a remainder of 729.
Record the quotient 3 as the next digit in the result. 
Result so far: 45192.103
Subtract 2571 from 3300 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Let's proceed to step 12:
The number 857 fits into 7290 8 times, leaving a remainder of 434.
Use 8 as the next digit of our solution. 
Result so far: 45192.1038
Subtracting 6856 from 7290 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 13:
857 can be fit into 4340 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 45192.10385
If we subtract 4285 from 4340, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
The number 857 fits into 550 0 times, leaving a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 45192.10385
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 15:
The number 857 fits into 5500 6 times, leaving a remainder of 358.
The next digit of our result is 6. 
Result so far: 45192.1038506
Deduct 5142 from 5500 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 16:
If we divide 3580 by 857, we get 4 and a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 45192.10385064
Subtract 3428 from 3580 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 45192.10385064 with a remaining 1.52e-07.
