Let's divide 54548086 by 870
We want to divide 54548086 by 870.

Step 1:
If we divide 5 by 870, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 870

Going ahead to step 2:
870 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 870

Moving on to step 3:
545 divided by 870 is 0 with a remainder of 545.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 545 leaves us with 545.
Append the next digit (4) from the dividend to 545 and continue with: 5454 / 870

Step 4:
When dividing 5454 by 870, we get 6 with a remainder of 234.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 234 after subtracting 5220 from 5454.
Take the next digit (8) from the dividend and append it to 234, then repeat: 2348 / 870

Advancing to step 5:
870 goes into 2348 2 times with a remainder of 608.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we subtract 1740 from 2348, we get 608.
Take the next digit (0) from the dividend and append it to 608, then repeat: 6080 / 870

Step 6:
870 can be fit into 6080 6 times, resulting in a remainder of 860.
Record the quotient 6 as the next digit in the result. 
Result so far: 626.0
Subtract 5220 from 6080 to get 860.
Include the next digit (8) from the dividend after 860, then repeat: 8608 / 870

Advancing to step 7:
870 can be fit into 8608 9 times, resulting in a remainder of 778.
The next digit of our result is 9. 
Result so far: 6269.0
If we subtract 7830 from 8608, we get 778.
Bring next digit (6) of the dividend behind the 778 and repeat the process: 7786 / 870

Step 8:
If we divide 7786 by 870, we get 8 and a remainder of 826.
Record the quotient 8 as the next digit in the result. 
Result so far: 62698.0
The remainder is 826 after subtracting 6960 from 7786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Moving on to step 9:
The number 870 fits into 8260 9 times, leaving a remainder of 430.
The number 9 becomes the next digit in our result. 
Result so far: 62698.9
If we subtract 7830 from 8260, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 10:
870 can be fit into 4300 4 times, resulting in a remainder of 820.
Put 4 as the next digit of the answer. 
Result so far: 62698.94
Deduct 3480 from 4300 and we're left with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 11:
If we divide 8200 by 870, we get 9 and a remainder of 370.
Write down 9 as next digit of the result. 
Result so far: 62698.949
Subtract 7830 from 8200 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 12:
The number 870 fits into 3700 4 times, leaving a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 62698.9494
Subtracting 3480 from 3700 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
870 goes into 2200 2 times with a remainder of 460.
Use 2 as the next digit of our solution. 
Result so far: 62698.94942
Deduct 1740 from 2200 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 14:
If we divide 4600 by 870, we get 5 and a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 62698.949425
If we take 4350 away from 4600, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
If we divide 2500 by 870, we get 2 and a remainder of 760.
Use 2 as the next digit of our solution. 
Result so far: 62698.9494252
Subtract 1740 from 2500 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 16:
The number 870 fits into 7600 8 times, leaving a remainder of 640.
The next digit of our result is 8. 
Result so far: 62698.94942528
Subtracting 6960 from 7600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

After the division, we end up with 62698.94942528 and a remainder of 6.4e-07.
