We're dividing 87373445 by 638 
We want to figure out the number of times 87373445 can be divided by 638.

On to step 1:
The number 638 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 638

Let's proceed to step 2:
87 divided by 638 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 638

Going ahead to step 3:
638 goes into 873 1 times with a remainder of 235.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 638 from 873 and we're left with 235.
Grab the next digit (7) from the dividend, add it to 235, then carry on: 2357 / 638

Let's proceed to step 4:
638 can be fit into 2357 3 times, resulting in a remainder of 443.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 443 after subtracting 1914 from 2357.
Include the next digit (3) from the dividend after 443, then repeat: 4433 / 638

Advancing to step 5:
When dividing 4433 by 638, we get 6 with a remainder of 605.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtracting 3828 from 4433 leaves us with 605.
Append the next digit (4) from the dividend to 605 and continue with: 6054 / 638

On to step 6:
The number 638 fits into 6054 9 times, leaving a remainder of 312.
Write down 9 as next digit of the result. 
Result so far: 1369.0
Subtracting 5742 from 6054 leaves us with 312.
Append the next digit (4) from the dividend to 312 and continue with: 3124 / 638

Let's proceed to step 7:
638 can be fit into 3124 4 times, resulting in a remainder of 572.
The next digit of our result is 4. 
Result so far: 13694.0
Subtract 2552 from 3124 to get 572.
Take the next digit (5) from the dividend and append it to 572, then repeat: 5725 / 638

Let's proceed to step 8:
638 can be fit into 5725 8 times, resulting in a remainder of 621.
The number 8 becomes the next digit in our result. 
Result so far: 136948.0
If we subtract 5104 from 5725, we get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Moving on to step 9:
6210 divided by 638 is 9 with a remainder of 468.
The next digit of our result is 9. 
Result so far: 136948.9
Deduct 5742 from 6210 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 10:
If we divide 4680 by 638, we get 7 and a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 136948.97
The remainder is 214 after subtracting 4466 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
When dividing 2140 by 638, we get 3 with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 136948.973
Subtracting 1914 from 2140 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 12:
If we divide 2260 by 638, we get 3 and a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 136948.9733
The remainder is 346 after subtracting 1914 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

In conclusion, the division gives 136948.9733 with a balance of 0.00346.
