Let's divide 53257137 by 870
Our goal is to divide 53257137 by 870.

Going ahead to step 1:
870 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 870

Moving on to step 2:
870 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 870

Step 3:
If we divide 532 by 870, we get 0 and a remainder of 532.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 532, we get 532.
Append the next digit (5) from the dividend to 532 and continue with: 5325 / 870

Advancing to step 4:
When dividing 5325 by 870, we get 6 with a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 5220 from 5325 to get 105.
Include the next digit (7) from the dividend after 105, then repeat: 1057 / 870

Advancing to step 5:
The number 870 fits into 1057 1 times, leaving a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtracting 870 from 1057 leaves us with 187.
Bring next digit (1) of the dividend behind the 187 and repeat the process: 1871 / 870

Moving on to step 6:
870 goes into 1871 2 times with a remainder of 131.
The number 2 becomes the next digit in our result. 
Result so far: 612.0
If we take 1740 away from 1871, we end up with 131.
Take the next digit (3) from the dividend and append it to 131, then repeat: 1313 / 870

Let's proceed to step 7:
When dividing 1313 by 870, we get 1 with a remainder of 443.
Use 1 as the next digit of our solution. 
Result so far: 6121.0
The remainder is 443 after subtracting 870 from 1313.
Bring next digit (7) of the dividend behind the 443 and repeat the process: 4437 / 870

Advancing to step 8:
The number 870 fits into 4437 5 times, leaving a remainder of 87.
The next digit of our result is 5. 
Result so far: 61215.0
The remainder is 87 after subtracting 4350 from 4437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
870 can be fit into 870 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 61215.1
The remainder is 0 after subtracting 870 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 870 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 61215.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 870 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 61215.1
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 61215.1 with a remaining 0.0.
