Let's divide 15485933 by 402
We want to figure out the number of times 15485933 can be divided by 402.

On to step 1:
402 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 402

Let's proceed to step 2:
402 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 402

Going ahead to step 3:
The number 402 fits into 154 0 times, leaving a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 154 leaves us with 154.
Bring next digit (8) of the dividend behind the 154 and repeat the process: 1548 / 402

Moving on to step 4:
1548 divided by 402 is 3 with a remainder of 342.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1206 from 1548 leaves us with 342.
Take the next digit (5) from the dividend and append it to 342, then repeat: 3425 / 402

Step 5:
When dividing 3425 by 402, we get 8 with a remainder of 209.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtract 3216 from 3425 to get 209.
Include the next digit (9) from the dividend after 209, then repeat: 2099 / 402

Going ahead to step 6:
402 can be fit into 2099 5 times, resulting in a remainder of 89.
Put 5 as the next digit of the answer. 
Result so far: 385.0
If we take 2010 away from 2099, we end up with 89.
Include the next digit (3) from the dividend after 89, then repeat: 893 / 402

On to step 7:
402 goes into 893 2 times with a remainder of 89.
Use 2 as the next digit of our solution. 
Result so far: 3852.0
The remainder is 89 after subtracting 804 from 893.
Append the next digit (3) from the dividend to 89 and continue with: 893 / 402

Going ahead to step 8:
893 divided by 402 is 2 with a remainder of 89.
Put 2 as the next digit of the answer. 
Result so far: 38522.0
Subtracting 804 from 893 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
402 goes into 890 2 times with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 38522.2
Subtracting 804 from 890 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 10:
402 can be fit into 860 2 times, resulting in a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 38522.22
Deduct 804 from 860 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 38522.22 with a remainder of 0.056.
