37888399 ÷ 638 
Let's see how many times 638 fits into 37888399.

Advancing to step 1:
3 divided by 638 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 638

Advancing to step 2:
If we divide 37 by 638, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 638

Moving on to step 3:
The number 638 fits into 378 0 times, leaving a remainder of 378.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 378 after subtracting 0 from 378.
Grab the next digit (8) from the dividend, add it to 378, then carry on: 3788 / 638

Let's proceed to step 4:
The number 638 fits into 3788 5 times, leaving a remainder of 598.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3190 from 3788 and we're left with 598.
Bring next digit (8) of the dividend behind the 598 and repeat the process: 5988 / 638

Advancing to step 5:
5988 divided by 638 is 9 with a remainder of 246.
The next digit of our result is 9. 
Result so far: 59.0
If we subtract 5742 from 5988, we get 246.
Grab the next digit (3) from the dividend, add it to 246, then carry on: 2463 / 638

Step 6:
When dividing 2463 by 638, we get 3 with a remainder of 549.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
Subtract 1914 from 2463 to get 549.
Fetch the next digit (9) from the dividend, attach it to 549 and continue: 5499 / 638

Going ahead to step 7:
638 can be fit into 5499 8 times, resulting in a remainder of 395.
Put 8 as the next digit of the answer. 
Result so far: 5938.0
The remainder is 395 after subtracting 5104 from 5499.
Fetch the next digit (9) from the dividend, attach it to 395 and continue: 3959 / 638

Going ahead to step 8:
638 goes into 3959 6 times with a remainder of 131.
The number 6 becomes the next digit in our result. 
Result so far: 59386.0
If we subtract 3828 from 3959, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
When dividing 1310 by 638, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 59386.2
Deduct 1276 from 1310 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
340 divided by 638 is 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 59386.2
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
638 goes into 3400 5 times with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 59386.205
If we take 3190 away from 3400, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 12:
If we divide 2100 by 638, we get 3 and a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 59386.2053
Deduct 1914 from 2100 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 13:
The number 638 fits into 1860 2 times, leaving a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 59386.20532
Subtracting 1276 from 1860 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 14:
The number 638 fits into 5840 9 times, leaving a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 59386.205329
Deduct 5742 from 5840 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 15:
980 divided by 638 is 1 with a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 59386.2053291
If we take 638 away from 980, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 16:
638 can be fit into 3420 5 times, resulting in a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 59386.20532915
The remainder is 230 after subtracting 3190 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The quotient of the division is 59386.20532915, and the remainder is 2.3e-07.
