We look at the division of 63919813 by 409 
We want to figure out the number of times 63919813 can be divided by 409.

Let's proceed to step 1:
6 divided by 409 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 409

Let's proceed to step 2:
The number 409 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 409

Moving on to step 3:
When dividing 639 by 409, we get 1 with a remainder of 230.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 409 from 639 to get 230.
Take the next digit (1) from the dividend and append it to 230, then repeat: 2301 / 409

Step 4:
2301 divided by 409 is 5 with a remainder of 256.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2045 from 2301 to get 256.
Fetch the next digit (9) from the dividend, attach it to 256 and continue: 2569 / 409

Let's proceed to step 5:
409 goes into 2569 6 times with a remainder of 115.
The next digit of our result is 6. 
Result so far: 156.0
The remainder is 115 after subtracting 2454 from 2569.
Fetch the next digit (8) from the dividend, attach it to 115 and continue: 1158 / 409

On to step 6:
The number 409 fits into 1158 2 times, leaving a remainder of 340.
The number 2 becomes the next digit in our result. 
Result so far: 1562.0
The remainder is 340 after subtracting 818 from 1158.
Fetch the next digit (1) from the dividend, attach it to 340 and continue: 3401 / 409

Step 7:
If we divide 3401 by 409, we get 8 and a remainder of 129.
The next digit of our result is 8. 
Result so far: 15628.0
The remainder is 129 after subtracting 3272 from 3401.
Take the next digit (3) from the dividend and append it to 129, then repeat: 1293 / 409

Going ahead to step 8:
1293 divided by 409 is 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 156283.0
If we subtract 1227 from 1293, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
409 can be fit into 660 1 times, resulting in a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 156283.1
The remainder is 251 after subtracting 409 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 10:
The number 409 fits into 2510 6 times, leaving a remainder of 56.
The next digit of our result is 6. 
Result so far: 156283.16
The remainder is 56 after subtracting 2454 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
409 can be fit into 560 1 times, resulting in a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 156283.161
Subtract 409 from 560 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 12:
If we divide 1510 by 409, we get 3 and a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 156283.1613
Subtracting 1227 from 1510 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 13:
2830 divided by 409 is 6 with a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 156283.16136
Subtract 2454 from 2830 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 14:
When dividing 3760 by 409, we get 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 156283.161369
If we take 3681 away from 3760, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 15:
When dividing 790 by 409, we get 1 with a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 156283.1613691
If we take 409 away from 790, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 16:
If we divide 3810 by 409, we get 9 and a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 156283.16136919
Subtracting 3681 from 3810 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final result is 156283.16136919 with a remainder of 1.29e-07.
