36993587 divided by 638 
Our goal is to divide 36993587 by 638.

Going ahead to step 1:
638 can be fit into 3 0 times, resulting in 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.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 638

Moving on to step 2:
638 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 638

Moving on to step 3:
When dividing 369 by 638, we get 0 with a remainder of 369.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 369 leaves us with 369.
Fetch the next digit (9) from the dividend, attach it to 369 and continue: 3699 / 638

Going ahead to step 4:
If we divide 3699 by 638, we get 5 and a remainder of 509.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3190 from 3699 and we're left with 509.
Grab the next digit (3) from the dividend, add it to 509, then carry on: 5093 / 638

On to step 5:
5093 divided by 638 is 7 with a remainder of 627.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 4466 away from 5093, we end up with 627.
Append the next digit (5) from the dividend to 627 and continue with: 6275 / 638

Going ahead to step 6:
If we divide 6275 by 638, we get 9 and a remainder of 533.
Record the quotient 9 as the next digit in the result. 
Result so far: 579.0
Subtracting 5742 from 6275 leaves us with 533.
Take the next digit (8) from the dividend and append it to 533, then repeat: 5338 / 638

On to step 7:
When dividing 5338 by 638, we get 8 with a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 5798.0
The remainder is 234 after subtracting 5104 from 5338.
Append the next digit (7) from the dividend to 234 and continue with: 2347 / 638

Step 8:
638 can be fit into 2347 3 times, resulting in a remainder of 433.
Write down 3 as next digit of the result. 
Result so far: 57983.0
The remainder is 433 after subtracting 1914 from 2347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 9:
The number 638 fits into 4330 6 times, leaving a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 57983.6
Subtracting 3828 from 4330 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 10:
When dividing 5020 by 638, we get 7 with a remainder of 554.
Record the quotient 7 as the next digit in the result. 
Result so far: 57983.67
Subtract 4466 from 5020 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 11:
638 goes into 5540 8 times with a remainder of 436.
Record the quotient 8 as the next digit in the result. 
Result so far: 57983.678
If we subtract 5104 from 5540, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 12:
When dividing 4360 by 638, we get 6 with a remainder of 532.
Record the quotient 6 as the next digit in the result. 
Result so far: 57983.6786
If we take 3828 away from 4360, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 13:
The number 638 fits into 5320 8 times, leaving a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 57983.67868
If we take 5104 away from 5320, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
2160 divided by 638 is 3 with a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 57983.678683
The remainder is 246 after subtracting 1914 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 15:
2460 divided by 638 is 3 with a remainder of 546.
The next digit of our result is 3. 
Result so far: 57983.6786833
Deduct 1914 from 2460 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

The final result is 57983.6786833 with a remainder of 5.46e-06.
