We're dividing 53319628 by 870 
We're looking to find how many times 870 goes into 53319628.

On to step 1:
5 divided by 870 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 870

Moving on to step 2:
If we divide 53 by 870, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 870

Let's proceed to step 3:
If we divide 533 by 870, we get 0 and a remainder of 533.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 533 after subtracting 0 from 533.
Take the next digit (1) from the dividend and append it to 533, then repeat: 5331 / 870

Let's proceed to step 4:
When dividing 5331 by 870, we get 6 with a remainder of 111.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5220 from 5331 and we're left with 111.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 870

Advancing to step 5:
870 goes into 1119 1 times with a remainder of 249.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 870 from 1119 leaves us with 249.
Include the next digit (6) from the dividend after 249, then repeat: 2496 / 870

Moving on to step 6:
2496 divided by 870 is 2 with a remainder of 756.
Write down 2 as next digit of the result. 
Result so far: 612.0
If we subtract 1740 from 2496, we get 756.
Bring next digit (2) of the dividend behind the 756 and repeat the process: 7562 / 870

Step 7:
The number 870 fits into 7562 8 times, leaving a remainder of 602.
Use 8 as the next digit of our solution. 
Result so far: 6128.0
If we take 6960 away from 7562, we end up with 602.
Append the next digit (8) from the dividend to 602 and continue with: 6028 / 870

Step 8:
870 goes into 6028 6 times with a remainder of 808.
The next digit of our result is 6. 
Result so far: 61286.0
If we subtract 5220 from 6028, we get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Moving on to step 9:
870 goes into 8080 9 times with a remainder of 250.
Use 9 as the next digit of our solution. 
Result so far: 61286.9
The remainder is 250 after subtracting 7830 from 8080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
When dividing 2500 by 870, we get 2 with a remainder of 760.
Put 2 as the next digit of the answer. 
Result so far: 61286.92
Subtracting 1740 from 2500 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 11:
870 can be fit into 7600 8 times, resulting in a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 61286.928
If we take 6960 away from 7600, we end up 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.

Going ahead to step 12:
870 can be fit into 6400 7 times, resulting in a remainder of 310.
The number 7 becomes the next digit in our result. 
Result so far: 61286.9287
Deduct 6090 from 6400 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 13:
If we divide 3100 by 870, we get 3 and a remainder of 490.
Record the quotient 3 as the next digit in the result. 
Result so far: 61286.92873
The remainder is 490 after subtracting 2610 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 14:
The number 870 fits into 4900 5 times, leaving a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 61286.928735
If we subtract 4350 from 4900, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 15:
5500 divided by 870 is 6 with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 61286.9287356
If we take 5220 away from 5500, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
2800 divided by 870 is 3 with a remainder of 190.
Write down 3 as next digit of the result. 
Result so far: 61286.92873563
Deduct 2610 from 2800 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 61286.92873563, with a leftover of 1.9e-07.
