82126734 ÷ 870 
Let's see how many times 870 fits into 82126734.

Moving on to step 1:
When dividing 8 by 870, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 870

On to step 2:
870 goes into 82 0 times with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 870

Going ahead to step 3:
870 goes into 821 0 times with a remainder of 821.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 821 to get 821.
Take the next digit (2) from the dividend and append it to 821, then repeat: 8212 / 870

Let's proceed to step 4:
If we divide 8212 by 870, we get 9 and a remainder of 382.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7830 from 8212, we get 382.
Append the next digit (6) from the dividend to 382 and continue with: 3826 / 870

Going ahead to step 5:
If we divide 3826 by 870, we get 4 and a remainder of 346.
Use 4 as the next digit of our solution. 
Result so far: 94.0
The remainder is 346 after subtracting 3480 from 3826.
Take the next digit (7) from the dividend and append it to 346, then repeat: 3467 / 870

Let's proceed to step 6:
3467 divided by 870 is 3 with a remainder of 857.
Use 3 as the next digit of our solution. 
Result so far: 943.0
The remainder is 857 after subtracting 2610 from 3467.
Bring next digit (3) of the dividend behind the 857 and repeat the process: 8573 / 870

On to step 7:
870 can be fit into 8573 9 times, resulting in a remainder of 743.
Record the quotient 9 as the next digit in the result. 
Result so far: 9439.0
If we take 7830 away from 8573, we end up with 743.
Fetch the next digit (4) from the dividend, attach it to 743 and continue: 7434 / 870

On to step 8:
870 can be fit into 7434 8 times, resulting in a remainder of 474.
The number 8 becomes the next digit in our result. 
Result so far: 94398.0
If we subtract 6960 from 7434, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
4740 divided by 870 is 5 with a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 94398.5
Subtracting 4350 from 4740 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
3900 divided by 870 is 4 with a remainder of 420.
Write down 4 as next digit of the result. 
Result so far: 94398.54
Deduct 3480 from 3900 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
The number 870 fits into 4200 4 times, leaving a remainder of 720.
The next digit of our result is 4. 
Result so far: 94398.544
If we take 3480 away from 4200, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

After the division, we end up with 94398.544 and a remainder of 0.072.
