11671499 divided by 870 
Our goal is to divide 11671499 by 870.

Step 1:
If we divide 1 by 870, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 870

On to step 2:
The number 870 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 870

On to step 3:
When dividing 116 by 870, we get 0 with a remainder of 116.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 116, we end up with 116.
Take the next digit (7) from the dividend and append it to 116, then repeat: 1167 / 870

Step 4:
870 can be fit into 1167 1 times, resulting in a remainder of 297.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 870 from 1167 leaves us with 297.
Take the next digit (1) from the dividend and append it to 297, then repeat: 2971 / 870

Moving on to step 5:
2971 divided by 870 is 3 with a remainder of 361.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 2610 from 2971 leaves us with 361.
Grab the next digit (4) from the dividend, add it to 361, then carry on: 3614 / 870

On to step 6:
When dividing 3614 by 870, we get 4 with a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 134.0
Subtracting 3480 from 3614 leaves us with 134.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 870

Let's proceed to step 7:
If we divide 1349 by 870, we get 1 and a remainder of 479.
Use 1 as the next digit of our solution. 
Result so far: 1341.0
The remainder is 479 after subtracting 870 from 1349.
Fetch the next digit (9) from the dividend, attach it to 479 and continue: 4799 / 870

On to step 8:
870 goes into 4799 5 times with a remainder of 449.
The next digit of our result is 5. 
Result so far: 13415.0
If we take 4350 away from 4799, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Advancing to step 9:
When dividing 4490 by 870, we get 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 13415.5
Deduct 4350 from 4490 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 870 fits into 1400 1 times, leaving a remainder of 530.
Put 1 as the next digit of the answer. 
Result so far: 13415.51
Subtract 870 from 1400 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
The number 870 fits into 5300 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 13415.516
If we take 5220 away from 5300, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
800 divided by 870 is 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 13415.516
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 13:
If we divide 8000 by 870, we get 9 and a remainder of 170.
Put 9 as the next digit of the answer. 
Result so far: 13415.51609
Deduct 7830 from 8000 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
The number 870 fits into 1700 1 times, leaving a remainder of 830.
Use 1 as the next digit of our solution. 
Result so far: 13415.516091
Deduct 870 from 1700 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Step 15:
870 can be fit into 8300 9 times, resulting in a remainder of 470.
The number 9 becomes the next digit in our result. 
Result so far: 13415.5160919
The remainder is 470 after subtracting 7830 from 8300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 16:
4700 divided by 870 is 5 with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 13415.51609195
Deduct 4350 from 4700 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

In conclusion, the division gives 13415.51609195 with a balance of 3.5e-07.
