Let's divide 81429401 by 19
We're looking to find how many times 19 goes into 81429401.

On to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 19

Advancing to step 2:
19 can be fit into 81 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 76 from 81, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 19

Let's proceed to step 3:
54 divided by 19 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 38 from 54 and we're left with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 19

Let's proceed to step 4:
19 can be fit into 162 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 428.0
If we take 152 away from 162, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 19

Step 5:
The number 19 fits into 109 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 4285.0
Subtract 95 from 109 to get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 19

Advancing to step 6:
The number 19 fits into 144 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 42857.0
Subtracting 133 from 144 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 19

Advancing to step 7:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 428575.0
If we subtract 95 from 110, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 19

Advancing to step 8:
151 divided by 19 is 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 4285757.0
The remainder is 18 after subtracting 133 from 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 4285757.9
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
When dividing 90 by 19, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4285757.94
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 4285757.947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
The number 19 fits into 70 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 4285757.9473
Subtracting 57 from 70 leaves us 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.

Advancing to step 13:
130 divided by 19 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 4285757.94736
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 19 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4285757.947368
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
80 divided by 19 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4285757.9473684
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 16:
40 divided by 19 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4285757.94736842
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 4285757.94736842 with a remaining 2e-09.
