We look at the division of 3852851 by 638 
We're looking to find how many times 638 goes into 3852851.

Advancing to step 1:
638 goes into 3 0 times with 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.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 638

Advancing to step 2:
638 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 638

Going ahead to step 3:
638 goes into 385 0 times with a remainder of 385.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 385, we get 385.
Include the next digit (2) from the dividend after 385, then repeat: 3852 / 638

Advancing to step 4:
When dividing 3852 by 638, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3828 from 3852 and we're left with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 638

Let's proceed to step 5:
638 can be fit into 248 0 times, resulting in a remainder of 248.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we subtract 0 from 248, we get 248.
Bring next digit (5) of the dividend behind the 248 and repeat the process: 2485 / 638

Moving on to step 6:
The number 638 fits into 2485 3 times, leaving a remainder of 571.
The number 3 becomes the next digit in our result. 
Result so far: 603.0
If we take 1914 away from 2485, we end up with 571.
Include the next digit (1) from the dividend after 571, then repeat: 5711 / 638

On to step 7:
When dividing 5711 by 638, we get 8 with a remainder of 607.
Put 8 as the next digit of the answer. 
Result so far: 6038.0
The remainder is 607 after subtracting 5104 from 5711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Advancing to step 8:
638 goes into 6070 9 times with a remainder of 328.
Record the quotient 9 as the next digit in the result. 
Result so far: 6038.9
Deduct 5742 from 6070 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 9:
638 can be fit into 3280 5 times, resulting in a remainder of 90.
The next digit of our result is 5. 
Result so far: 6038.95
Subtracting 3190 from 3280 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
638 can be fit into 900 1 times, resulting in a remainder of 262.
The next digit of our result is 1. 
Result so far: 6038.951
The remainder is 262 after subtracting 638 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 11:
When dividing 2620 by 638, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 6038.9514
Subtracting 2552 from 2620 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
If we divide 680 by 638, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 6038.95141
If we subtract 638 from 680, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
638 can be fit into 420 0 times, resulting in a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 6038.95141
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 14:
4200 divided by 638 is 6 with a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 6038.9514106
Deduct 3828 from 4200 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 15:
3720 divided by 638 is 5 with a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 6038.95141065
If we subtract 3190 from 3720, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The quotient of the division is 6038.95141065, and the remainder is 5.3e-07.
