We're dividing 72152310 by 419 
Let's see how many times 419 fits into 72152310.

Step 1:
If we divide 7 by 419, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 419

Let's proceed to step 2:
When dividing 72 by 419, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 419

Advancing to step 3:
When dividing 721 by 419, we get 1 with a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 302 after subtracting 419 from 721.
Include the next digit (5) from the dividend after 302, then repeat: 3025 / 419

Going ahead to step 4:
If we divide 3025 by 419, we get 7 and a remainder of 92.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 2933 from 3025 to get 92.
Take the next digit (2) from the dividend and append it to 92, then repeat: 922 / 419

Step 5:
419 goes into 922 2 times with a remainder of 84.
The next digit of our result is 2. 
Result so far: 172.0
If we subtract 838 from 922, we get 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 419

On to step 6:
419 can be fit into 843 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 1722.0
Deduct 838 from 843 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 419

Going ahead to step 7:
51 divided by 419 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 17220.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 419

Advancing to step 8:
The number 419 fits into 510 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 172201.0
The remainder is 91 after subtracting 419 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
419 goes into 910 2 times with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 172201.2
The remainder is 72 after subtracting 838 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
When dividing 720 by 419, we get 1 with a remainder of 301.
The next digit of our result is 1. 
Result so far: 172201.21
Subtracting 419 from 720 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 11:
If we divide 3010 by 419, we get 7 and a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 172201.217
Subtract 2933 from 3010 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
419 can be fit into 770 1 times, resulting in a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 172201.2171
Subtract 419 from 770 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 13:
3510 divided by 419 is 8 with a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 172201.21718
Subtracting 3352 from 3510 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 14:
The number 419 fits into 1580 3 times, leaving a remainder of 323.
Record the quotient 3 as the next digit in the result. 
Result so far: 172201.217183
Deduct 1257 from 1580 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 15:
419 goes into 3230 7 times with a remainder of 297.
Write down 7 as next digit of the result. 
Result so far: 172201.2171837
Subtracting 2933 from 3230 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 16:
When dividing 2970 by 419, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 172201.21718377
Subtracting 2933 from 2970 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 172201.21718377 with a remaining 3.7e-08.
