53917193 divided by 638 
Our goal is to divide 53917193 by 638.

Let's proceed to step 1:
638 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 638

Step 2:
When dividing 53 by 638, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 638

Going ahead to step 3:
638 goes into 539 0 times with a remainder of 539.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 539 and we're left with 539.
Take the next digit (1) from the dividend and append it to 539, then repeat: 5391 / 638

Advancing to step 4:
638 can be fit into 5391 8 times, resulting in a remainder of 287.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 5104 from 5391 to get 287.
Bring next digit (7) of the dividend behind the 287 and repeat the process: 2877 / 638

Step 5:
2877 divided by 638 is 4 with a remainder of 325.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 2552 from 2877 and we're left with 325.
Take the next digit (1) from the dividend and append it to 325, then repeat: 3251 / 638

Moving on to step 6:
638 goes into 3251 5 times with a remainder of 61.
Put 5 as the next digit of the answer. 
Result so far: 845.0
Subtract 3190 from 3251 to get 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 638

Step 7:
619 divided by 638 is 0 with a remainder of 619.
Put 0 as the next digit of the answer. 
Result so far: 8450.0
If we take 0 away from 619, we end up with 619.
Append the next digit (3) from the dividend to 619 and continue with: 6193 / 638

On to step 8:
6193 divided by 638 is 9 with a remainder of 451.
The next digit of our result is 9. 
Result so far: 84509.0
Subtract 5742 from 6193 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 9:
638 can be fit into 4510 7 times, resulting in a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 84509.7
Deduct 4466 from 4510 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
638 goes into 440 0 times with a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 84509.7
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
The number 638 fits into 4400 6 times, leaving a remainder of 572.
The number 6 becomes the next digit in our result. 
Result so far: 84509.706
If we take 3828 away from 4400, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 12:
When dividing 5720 by 638, we get 8 with a remainder of 616.
The next digit of our result is 8. 
Result so far: 84509.7068
The remainder is 616 after subtracting 5104 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 13:
If we divide 6160 by 638, we get 9 and a remainder of 418.
The next digit of our result is 9. 
Result so far: 84509.70689
Subtract 5742 from 6160 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 14:
The number 638 fits into 4180 6 times, leaving a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 84509.706896
If we subtract 3828 from 4180, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 15:
638 can be fit into 3520 5 times, resulting in a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 84509.7068965
Deduct 3190 from 3520 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.

Step 16:
If we divide 3300 by 638, we get 5 and a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 84509.70689655
Deduct 3190 from 3300 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 84509.70689655 with a balance of 1.1e-07.
