Let's divide 638434 by 87
We're looking to find how many times 87 goes into 638434.

Let's proceed to step 1:
87 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 87

Moving on to step 2:
87 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 87

Let's proceed to step 3:
87 goes into 638 7 times with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 609 from 638, we get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 87

Advancing to step 4:
87 goes into 294 3 times with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we subtract 261 from 294, we get 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 87

Step 5:
333 divided by 87 is 3 with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 733.0
If we subtract 261 from 333, we get 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 87

Step 6:
724 divided by 87 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 7338.0
Subtracting 696 from 724 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
87 goes into 280 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 7338.3
Subtracting 261 from 280 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
87 goes into 190 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 7338.32
Subtracting 174 from 190 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
87 goes into 160 1 times with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 7338.321
If we subtract 87 from 160, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
If we divide 730 by 87, we get 8 and a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 7338.3218
Subtract 696 from 730 to get 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 11:
340 divided by 87 is 3 with a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 7338.32183
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 12:
790 divided by 87 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 7338.321839
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
70 divided by 87 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 7338.321839
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
When dividing 700 by 87, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 7338.32183908
Deduct 696 from 700 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 7338.32183908 with a remainder of 4e-09.
