15858163 ÷ 758 
Let's see how many times 758 fits into 15858163.

On to step 1:
If we divide 1 by 758, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 758

Step 2:
The number 758 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 758

Let's proceed to step 3:
758 can be fit into 158 0 times, resulting in a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Append the next digit (5) from the dividend to 158 and continue with: 1585 / 758

On to step 4:
1585 divided by 758 is 2 with a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1516 away from 1585, we end up with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 758

Moving on to step 5:
If we divide 698 by 758, we get 0 and a remainder of 698.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 698 to get 698.
Fetch the next digit (1) from the dividend, attach it to 698 and continue: 6981 / 758

Going ahead to step 6:
758 goes into 6981 9 times with a remainder of 159.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
If we take 6822 away from 6981, we end up with 159.
Fetch the next digit (6) from the dividend, attach it to 159 and continue: 1596 / 758

Moving on to step 7:
If we divide 1596 by 758, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 2092.0
Deduct 1516 from 1596 and we're left with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 758

Moving on to step 8:
When dividing 803 by 758, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 20921.0
The remainder is 45 after subtracting 758 from 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
The number 758 fits into 450 0 times, leaving a remainder of 450.
The next digit of our result is 0. 
Result so far: 20921.0
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
If we divide 4500 by 758, we get 5 and a remainder of 710.
Record the quotient 5 as the next digit in the result. 
Result so far: 20921.05
Subtract 3790 from 4500 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 11:
The number 758 fits into 7100 9 times, leaving a remainder of 278.
Write down 9 as next digit of the result. 
Result so far: 20921.059
If we take 6822 away from 7100, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 12:
758 can be fit into 2780 3 times, resulting in a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 20921.0593
If we take 2274 away from 2780, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 13:
If we divide 5060 by 758, we get 6 and a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 20921.05936
The remainder is 512 after subtracting 4548 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 14:
The number 758 fits into 5120 6 times, leaving a remainder of 572.
Write down 6 as next digit of the result. 
Result so far: 20921.059366
The remainder is 572 after subtracting 4548 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The final result is 20921.059366 with a remainder of 5.72e-05.
