We look at the division of 81419251 by 189 
Our goal is to divide 81419251 by 189.

On to step 1:
189 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 189

Step 2:
When dividing 81 by 189, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 189

Advancing to step 3:
189 can be fit into 814 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 756 from 814 to get 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 189

Let's proceed to step 4:
The number 189 fits into 581 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 567 away from 581, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 189

Advancing to step 5:
189 goes into 149 0 times with a remainder of 149.
Put 0 as the next digit of the answer. 
Result so far: 430.0
If we subtract 0 from 149, we get 149.
Grab the next digit (2) from the dividend, add it to 149, then carry on: 1492 / 189

Step 6:
If we divide 1492 by 189, we get 7 and a remainder of 169.
Record the quotient 7 as the next digit in the result. 
Result so far: 4307.0
The remainder is 169 after subtracting 1323 from 1492.
Take the next digit (5) from the dividend and append it to 169, then repeat: 1695 / 189

Let's proceed to step 7:
189 can be fit into 1695 8 times, resulting in a remainder of 183.
Put 8 as the next digit of the answer. 
Result so far: 43078.0
Deduct 1512 from 1695 and we're left with 183.
Grab the next digit (1) from the dividend, add it to 183, then carry on: 1831 / 189

Let's proceed to step 8:
If we divide 1831 by 189, we get 9 and a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 430789.0
Subtracting 1701 from 1831 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
The number 189 fits into 1300 6 times, leaving a remainder of 166.
The number 6 becomes the next digit in our result. 
Result so far: 430789.6
Deduct 1134 from 1300 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 10:
If we divide 1660 by 189, we get 8 and a remainder of 148.
Use 8 as the next digit of our solution. 
Result so far: 430789.68
Subtract 1512 from 1660 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 11:
The number 189 fits into 1480 7 times, leaving a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 430789.687
If we subtract 1323 from 1480, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 12:
When dividing 1570 by 189, we get 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 430789.6878
Deduct 1512 from 1570 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
The number 189 fits into 580 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 430789.68783
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
When dividing 130 by 189, we get 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 430789.68783
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 15:
1300 divided by 189 is 6 with a remainder of 166.
Use 6 as the next digit of our solution. 
Result so far: 430789.6878306
Subtracting 1134 from 1300 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 16:
189 goes into 1660 8 times with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 430789.68783068
The remainder is 148 after subtracting 1512 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

In conclusion, the division gives 430789.68783068 with a balance of 1.48e-07.
