Let's divide 4143572 by 419
We want to divide 4143572 by 419.

On to step 1:
4 divided by 419 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 419

Moving on to step 2:
419 can be fit into 41 0 times, resulting in a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 419

Step 3:
The number 419 fits into 414 0 times, leaving a remainder of 414.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 414 and we're left with 414.
Include the next digit (3) from the dividend after 414, then repeat: 4143 / 419

Going ahead to step 4:
If we divide 4143 by 419, we get 9 and a remainder of 372.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 3771 from 4143 leaves us with 372.
Include the next digit (5) from the dividend after 372, then repeat: 3725 / 419

Going ahead to step 5:
If we divide 3725 by 419, we get 8 and a remainder of 373.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 3352 from 3725 and we're left with 373.
Take the next digit (7) from the dividend and append it to 373, then repeat: 3737 / 419

Let's proceed to step 6:
419 can be fit into 3737 8 times, resulting in a remainder of 385.
The next digit of our result is 8. 
Result so far: 988.0
Subtract 3352 from 3737 to get 385.
Take the next digit (2) from the dividend and append it to 385, then repeat: 3852 / 419

On to step 7:
The number 419 fits into 3852 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 9889.0
Deduct 3771 from 3852 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 8:
419 goes into 810 1 times with a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 9889.1
Deduct 419 from 810 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 9:
419 can be fit into 3910 9 times, resulting in a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 9889.19
Subtract 3771 from 3910 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
The number 419 fits into 1390 3 times, leaving a remainder of 133.
Write down 3 as next digit of the result. 
Result so far: 9889.193
If we take 1257 away from 1390, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 11:
419 can be fit into 1330 3 times, resulting in a remainder of 73.
The next digit of our result is 3. 
Result so far: 9889.1933
If we subtract 1257 from 1330, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

In conclusion, the division gives 9889.1933 with a balance of 0.00073.
