We look at the division of 39009169 by 402 
We want to figure out the number of times 39009169 can be divided by 402.

On to step 1:
When dividing 3 by 402, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 402

Going ahead to step 2:
The number 402 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 402

On to step 3:
402 goes into 390 0 times with a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 390 to get 390.
Grab the next digit (0) from the dividend, add it to 390, then carry on: 3900 / 402

Advancing to step 4:
The number 402 fits into 3900 9 times, leaving a remainder of 282.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 282 after subtracting 3618 from 3900.
Append the next digit (9) from the dividend to 282 and continue with: 2829 / 402

Moving on to step 5:
The number 402 fits into 2829 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 2814 from 2829 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 402

Moving on to step 6:
151 divided by 402 is 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 970.0
The remainder is 151 after subtracting 0 from 151.
Bring next digit (6) of the dividend behind the 151 and repeat the process: 1516 / 402

Going ahead to step 7:
If we divide 1516 by 402, we get 3 and a remainder of 310.
Record the quotient 3 as the next digit in the result. 
Result so far: 9703.0
If we take 1206 away from 1516, we end up with 310.
Fetch the next digit (9) from the dividend, attach it to 310 and continue: 3109 / 402

Step 8:
402 goes into 3109 7 times with a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 97037.0
If we subtract 2814 from 3109, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 9:
When dividing 2950 by 402, we get 7 with a remainder of 136.
Put 7 as the next digit of the answer. 
Result so far: 97037.7
Deduct 2814 from 2950 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
If we divide 1360 by 402, we get 3 and a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 97037.73
If we take 1206 away from 1360, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 11:
The number 402 fits into 1540 3 times, leaving a remainder of 334.
Put 3 as the next digit of the answer. 
Result so far: 97037.733
Subtract 1206 from 1540 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

In conclusion, the division gives 97037.733 with a balance of 0.0334.
