We look at the division of 4125478 by 87 
Let's see how many times 87 fits into 4125478.

Advancing to step 1:
The number 87 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 87

On to step 2:
41 divided by 87 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 87

Moving on to step 3:
If we divide 412 by 87, we get 4 and a remainder of 64.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 348 from 412 to get 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 87

Let's proceed to step 4:
When dividing 645 by 87, we get 7 with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 609 from 645, we get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 87

On to step 5:
87 can be fit into 364 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 474.0
If we take 348 away from 364, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 87

Step 6:
If we divide 167 by 87, we get 1 and a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 4741.0
If we subtract 87 from 167, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 87

Advancing to step 7:
808 divided by 87 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 47419.0
The remainder is 25 after subtracting 783 from 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
When dividing 250 by 87, we get 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 47419.2
If we take 174 away from 250, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
87 goes into 760 8 times with a remainder of 64.
The next digit of our result is 8. 
Result so far: 47419.28
Subtracting 696 from 760 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
When dividing 640 by 87, we get 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 47419.287
The remainder is 31 after subtracting 609 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
If we divide 310 by 87, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 47419.2873
Subtracting 261 from 310 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
490 divided by 87 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 47419.28735
If we take 435 away from 490, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
If we divide 550 by 87, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 47419.287356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 47419.2873563
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 15:
When dividing 190 by 87, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 47419.28735632
Subtract 174 from 190 to 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.

The final result is 47419.28735632 with a remainder of 1.6e-08.
