We're dividing 5186399 by 429 
We're looking to find how many times 429 goes into 5186399.

Moving on to step 1:
429 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 429

Moving on to step 2:
429 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 429

Step 3:
When dividing 518 by 429, we get 1 with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 429 from 518 to get 89.
Include the next digit (6) from the dividend after 89, then repeat: 896 / 429

On to step 4:
896 divided by 429 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 858 away from 896, we end up with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 429

Step 5:
The number 429 fits into 383 0 times, leaving a remainder of 383.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
The remainder is 383 after subtracting 0 from 383.
Include the next digit (9) from the dividend after 383, then repeat: 3839 / 429

On to step 6:
When dividing 3839 by 429, we get 8 with a remainder of 407.
The next digit of our result is 8. 
Result so far: 1208.0
If we subtract 3432 from 3839, we get 407.
Take the next digit (9) from the dividend and append it to 407, then repeat: 4079 / 429

Moving on to step 7:
429 goes into 4079 9 times with a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 12089.0
If we subtract 3861 from 4079, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 8:
If we divide 2180 by 429, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 12089.5
If we subtract 2145 from 2180, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
429 can be fit into 350 0 times, resulting in a remainder of 350.
The next digit of our result is 0. 
Result so far: 12089.5
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 10:
429 goes into 3500 8 times with a remainder of 68.
The next digit of our result is 8. 
Result so far: 12089.508
Deduct 3432 from 3500 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
When dividing 680 by 429, we get 1 with a remainder of 251.
The next digit of our result is 1. 
Result so far: 12089.5081
If we take 429 away from 680, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 12:
429 goes into 2510 5 times with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 12089.50815
If we take 2145 away from 2510, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 13:
429 can be fit into 3650 8 times, resulting in a remainder of 218.
The number 8 becomes the next digit in our result. 
Result so far: 12089.508158
If we take 3432 away from 3650, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 14:
If we divide 2180 by 429, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 12089.5081585
Subtract 2145 from 2180 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 15:
The number 429 fits into 350 0 times, leaving a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 12089.5081585
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

In conclusion, the division gives 12089.5081585 with a balance of 3.5e-07.
