73298911 ÷ 870 
Let's see how many times 870 fits into 73298911.

Going ahead to step 1:
870 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 870

Advancing to step 2:
When dividing 73 by 870, we get 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 870

Advancing to step 3:
870 can be fit into 732 0 times, resulting in a remainder of 732.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 732 to get 732.
Include the next digit (9) from the dividend after 732, then repeat: 7329 / 870

Let's proceed to step 4:
The number 870 fits into 7329 8 times, leaving a remainder of 369.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6960 from 7329, we get 369.
Grab the next digit (8) from the dividend, add it to 369, then carry on: 3698 / 870

On to step 5:
3698 divided by 870 is 4 with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 3480 from 3698 to get 218.
Include the next digit (9) from the dividend after 218, then repeat: 2189 / 870

Let's proceed to step 6:
When dividing 2189 by 870, we get 2 with a remainder of 449.
Use 2 as the next digit of our solution. 
Result so far: 842.0
Subtracting 1740 from 2189 leaves us with 449.
Append the next digit (1) from the dividend to 449 and continue with: 4491 / 870

On to step 7:
When dividing 4491 by 870, we get 5 with a remainder of 141.
Write down 5 as next digit of the result. 
Result so far: 8425.0
Subtract 4350 from 4491 to get 141.
Grab the next digit (1) from the dividend, add it to 141, then carry on: 1411 / 870

Let's proceed to step 8:
870 goes into 1411 1 times with a remainder of 541.
Write down 1 as next digit of the result. 
Result so far: 84251.0
Subtract 870 from 1411 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Advancing to step 9:
The number 870 fits into 5410 6 times, leaving a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 84251.6
Deduct 5220 from 5410 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.

Advancing to step 10:
870 can be fit into 1900 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 84251.62
If we subtract 1740 from 1900, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
When dividing 1600 by 870, we get 1 with a remainder of 730.
The next digit of our result is 1. 
Result so far: 84251.621
Subtracting 870 from 1600 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 12:
The number 870 fits into 7300 8 times, leaving a remainder of 340.
The number 8 becomes the next digit in our result. 
Result so far: 84251.6218
Deduct 6960 from 7300 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 13:
The number 870 fits into 3400 3 times, leaving a remainder of 790.
Put 3 as the next digit of the answer. 
Result so far: 84251.62183
The remainder is 790 after subtracting 2610 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 14:
7900 divided by 870 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 84251.621839
Deduct 7830 from 7900 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
700 divided by 870 is 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 84251.621839
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 16:
When dividing 7000 by 870, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 84251.62183908
If we take 6960 away from 7000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 84251.62183908 with a balance of 4e-08.
