We look at the division of 54251613 by 870 
We want to divide 54251613 by 870.

Let's proceed to step 1:
870 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 870

Going ahead to step 2:
If we divide 54 by 870, we get 0 and a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 870

Let's proceed to step 3:
542 divided by 870 is 0 with a remainder of 542.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 542, we get 542.
Take the next digit (5) from the dividend and append it to 542, then repeat: 5425 / 870

Going ahead to step 4:
The number 870 fits into 5425 6 times, leaving a remainder of 205.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5220 away from 5425, we end up with 205.
Bring next digit (1) of the dividend behind the 205 and repeat the process: 2051 / 870

Moving on to step 5:
2051 divided by 870 is 2 with a remainder of 311.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 1740 from 2051 leaves us with 311.
Grab the next digit (6) from the dividend, add it to 311, then carry on: 3116 / 870

Step 6:
3116 divided by 870 is 3 with a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 623.0
If we subtract 2610 from 3116, we get 506.
Grab the next digit (1) from the dividend, add it to 506, then carry on: 5061 / 870

On to step 7:
870 goes into 5061 5 times with a remainder of 711.
The next digit of our result is 5. 
Result so far: 6235.0
The remainder is 711 after subtracting 4350 from 5061.
Bring next digit (3) of the dividend behind the 711 and repeat the process: 7113 / 870

Advancing to step 8:
When dividing 7113 by 870, we get 8 with a remainder of 153.
Put 8 as the next digit of the answer. 
Result so far: 62358.0
If we subtract 6960 from 7113, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 9:
The number 870 fits into 1530 1 times, leaving a remainder of 660.
Write down 1 as next digit of the result. 
Result so far: 62358.1
Subtract 870 from 1530 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 10:
870 can be fit into 6600 7 times, resulting in a remainder of 510.
The next digit of our result is 7. 
Result so far: 62358.17
If we take 6090 away from 6600, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 11:
If we divide 5100 by 870, we get 5 and a remainder of 750.
Write down 5 as next digit of the result. 
Result so far: 62358.175
If we subtract 4350 from 5100, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 12:
The number 870 fits into 7500 8 times, leaving a remainder of 540.
Write down 8 as next digit of the result. 
Result so far: 62358.1758
If we take 6960 away from 7500, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 13:
If we divide 5400 by 870, we get 6 and a remainder of 180.
The next digit of our result is 6. 
Result so far: 62358.17586
Subtract 5220 from 5400 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
870 can be fit into 1800 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 62358.175862
The remainder is 60 after subtracting 1740 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 15:
600 divided by 870 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 62358.175862
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 16:
When dividing 6000 by 870, we get 6 with a remainder of 780.
Put 6 as the next digit of the answer. 
Result so far: 62358.17586206
If we subtract 5220 from 6000, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

After the division, we end up with 62358.17586206 and a remainder of 7.8e-07.
