We're dividing 43426788 by 870 
We're looking to find how many times 870 goes into 43426788.

On to step 1:
870 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 870

On to step 2:
870 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 870

Step 3:
If we divide 434 by 870, we get 0 and a remainder of 434.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 434 leaves us with 434.
Grab the next digit (2) from the dividend, add it to 434, then carry on: 4342 / 870

Moving on to step 4:
870 goes into 4342 4 times with a remainder of 862.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3480 from 4342 and we're left with 862.
Include the next digit (6) from the dividend after 862, then repeat: 8626 / 870

Step 5:
When dividing 8626 by 870, we get 9 with a remainder of 796.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 7830 from 8626, we get 796.
Include the next digit (7) from the dividend after 796, then repeat: 7967 / 870

On to step 6:
If we divide 7967 by 870, we get 9 and a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 499.0
Deduct 7830 from 7967 and we're left with 137.
Include the next digit (8) from the dividend after 137, then repeat: 1378 / 870

On to step 7:
If we divide 1378 by 870, we get 1 and a remainder of 508.
Use 1 as the next digit of our solution. 
Result so far: 4991.0
Subtracting 870 from 1378 leaves us with 508.
Take the next digit (8) from the dividend and append it to 508, then repeat: 5088 / 870

Let's proceed to step 8:
When dividing 5088 by 870, we get 5 with a remainder of 738.
The number 5 becomes the next digit in our result. 
Result so far: 49915.0
Subtract 4350 from 5088 to get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Step 9:
The number 870 fits into 7380 8 times, leaving a remainder of 420.
The next digit of our result is 8. 
Result so far: 49915.8
If we subtract 6960 from 7380, we get 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 10:
870 goes into 4200 4 times with a remainder of 720.
Write down 4 as next digit of the result. 
Result so far: 49915.84
The remainder is 720 after subtracting 3480 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 11:
870 can be fit into 7200 8 times, resulting in a remainder of 240.
The next digit of our result is 8. 
Result so far: 49915.848
Deduct 6960 from 7200 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 12:
If we divide 2400 by 870, we get 2 and a remainder of 660.
The number 2 becomes the next digit in our result. 
Result so far: 49915.8482
Deduct 1740 from 2400 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 13:
The number 870 fits into 6600 7 times, leaving a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 49915.84827
Subtracting 6090 from 6600 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 14:
870 goes into 5100 5 times with a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 49915.848275
If we take 4350 away from 5100, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 15:
When dividing 7500 by 870, we get 8 with a remainder of 540.
Use 8 as the next digit of our solution. 
Result so far: 49915.8482758
Deduct 6960 from 7500 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 16:
The number 870 fits into 5400 6 times, leaving a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 49915.84827586
Subtract 5220 from 5400 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 49915.84827586, and the remainder is 1.8e-07.
