We look at the division of 6413592 by 402 
We want to figure out the number of times 6413592 can be divided by 402.

Step 1:
If we divide 6 by 402, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 402

Moving on to step 2:
402 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 402

Moving on to step 3:
When dividing 641 by 402, we get 1 with a remainder of 239.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 402 from 641 leaves us with 239.
Bring next digit (3) of the dividend behind the 239 and repeat the process: 2393 / 402

On to step 4:
The number 402 fits into 2393 5 times, leaving a remainder of 383.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2010 away from 2393, we end up with 383.
Fetch the next digit (5) from the dividend, attach it to 383 and continue: 3835 / 402

On to step 5:
402 can be fit into 3835 9 times, resulting in a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Deduct 3618 from 3835 and we're left with 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 402

On to step 6:
402 goes into 2179 5 times with a remainder of 169.
The number 5 becomes the next digit in our result. 
Result so far: 1595.0
Deduct 2010 from 2179 and we're left with 169.
Grab the next digit (2) from the dividend, add it to 169, then carry on: 1692 / 402

Going ahead to step 7:
If we divide 1692 by 402, we get 4 and a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 15954.0
The remainder is 84 after subtracting 1608 from 1692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
840 divided by 402 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 15954.2
Subtract 804 from 840 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 402 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 15954.2
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 402, we get 8 and a remainder of 384.
Use 8 as the next digit of our solution. 
Result so far: 15954.208
If we take 3216 away from 3600, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 11:
The number 402 fits into 3840 9 times, leaving a remainder of 222.
The next digit of our result is 9. 
Result so far: 15954.2089
The remainder is 222 after subtracting 3618 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 12:
2220 divided by 402 is 5 with a remainder of 210.
The next digit of our result is 5. 
Result so far: 15954.20895
If we take 2010 away from 2220, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
402 goes into 2100 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 15954.208955
Subtract 2010 from 2100 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 15954.208955, with a leftover of 9e-06.
