67251253 ÷ 638 
Our goal is to divide 67251253 by 638.

Going ahead to step 1:
When dividing 6 by 638, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 638

Let's proceed to step 2:
67 divided by 638 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 638

Going ahead to step 3:
672 divided by 638 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 638 from 672, we get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 638

On to step 4:
When dividing 345 by 638, we get 0 with a remainder of 345.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 345, we get 345.
Take the next digit (1) from the dividend and append it to 345, then repeat: 3451 / 638

Going ahead to step 5:
When dividing 3451 by 638, we get 5 with a remainder of 261.
The next digit of our result is 5. 
Result so far: 105.0
Subtracting 3190 from 3451 leaves us with 261.
Include the next digit (2) from the dividend after 261, then repeat: 2612 / 638

Advancing to step 6:
When dividing 2612 by 638, we get 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1054.0
If we take 2552 away from 2612, we end up with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 638

Going ahead to step 7:
605 divided by 638 is 0 with a remainder of 605.
Put 0 as the next digit of the answer. 
Result so far: 10540.0
If we subtract 0 from 605, we get 605.
Bring next digit (3) of the dividend behind the 605 and repeat the process: 6053 / 638

Advancing to step 8:
638 can be fit into 6053 9 times, resulting in a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 105409.0
Deduct 5742 from 6053 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 9:
638 goes into 3110 4 times with a remainder of 558.
Use 4 as the next digit of our solution. 
Result so far: 105409.4
If we take 2552 away from 3110, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 10:
The number 638 fits into 5580 8 times, leaving a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 105409.48
Deduct 5104 from 5580 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 11:
4760 divided by 638 is 7 with a remainder of 294.
Record the quotient 7 as the next digit in the result. 
Result so far: 105409.487
Subtracting 4466 from 4760 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 12:
638 goes into 2940 4 times with a remainder of 388.
The number 4 becomes the next digit in our result. 
Result so far: 105409.4874
Deduct 2552 from 2940 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 13:
When dividing 3880 by 638, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 105409.48746
Subtracting 3828 from 3880 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
When dividing 520 by 638, we get 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 105409.48746
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 15:
638 goes into 5200 8 times with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 105409.4874608
If we take 5104 away from 5200, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
638 goes into 960 1 times with a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 105409.48746081
If we take 638 away from 960, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The quotient of the division is 105409.48746081, and the remainder is 3.22e-07.
