Let's divide 97213066 by 638
We're looking to find how many times 638 goes into 97213066.

Going ahead to step 1:
If we divide 9 by 638, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 638

Advancing to step 2:
638 can be fit into 97 0 times, resulting in a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Bring next digit (2) of the dividend behind the 97 and repeat the process: 972 / 638

Going ahead to step 3:
972 divided by 638 is 1 with a remainder of 334.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 638 from 972 and we're left with 334.
Bring next digit (1) of the dividend behind the 334 and repeat the process: 3341 / 638

Going ahead to step 4:
The number 638 fits into 3341 5 times, leaving a remainder of 151.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 151 after subtracting 3190 from 3341.
Fetch the next digit (3) from the dividend, attach it to 151 and continue: 1513 / 638

Step 5:
When dividing 1513 by 638, we get 2 with a remainder of 237.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we take 1276 away from 1513, we end up with 237.
Append the next digit (0) from the dividend to 237 and continue with: 2370 / 638

Going ahead to step 6:
638 goes into 2370 3 times with a remainder of 456.
Write down 3 as next digit of the result. 
Result so far: 1523.0
Subtracting 1914 from 2370 leaves us with 456.
Fetch the next digit (6) from the dividend, attach it to 456 and continue: 4566 / 638

Let's proceed to step 7:
If we divide 4566 by 638, we get 7 and a remainder of 100.
Use 7 as the next digit of our solution. 
Result so far: 15237.0
If we subtract 4466 from 4566, we get 100.
Append the next digit (6) from the dividend to 100 and continue with: 1006 / 638

Step 8:
638 can be fit into 1006 1 times, resulting in a remainder of 368.
The number 1 becomes the next digit in our result. 
Result so far: 152371.0
Deduct 638 from 1006 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
638 goes into 3680 5 times with a remainder of 490.
Write down 5 as next digit of the result. 
Result so far: 152371.5
If we take 3190 away from 3680, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 10:
If we divide 4900 by 638, we get 7 and a remainder of 434.
Record the quotient 7 as the next digit in the result. 
Result so far: 152371.57
Subtract 4466 from 4900 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 11:
The number 638 fits into 4340 6 times, leaving a remainder of 512.
Write down 6 as next digit of the result. 
Result so far: 152371.576
Deduct 3828 from 4340 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 12:
5120 divided by 638 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 152371.5768
If we subtract 5104 from 5120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 638 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 152371.5768
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
638 can be fit into 1600 2 times, resulting in a remainder of 324.
The next digit of our result is 2. 
Result so far: 152371.576802
If we take 1276 away from 1600, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 15:
3240 divided by 638 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 152371.5768025
If we take 3190 away from 3240, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 16:
500 divided by 638 is 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 152371.5768025
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 152371.5768025 with a balance of 5e-07.
