We're dividing 851531 by 19 
We're looking to find how many times 19 goes into 851531.

Let's proceed to step 1:
The number 19 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 19

Step 2:
The number 19 fits into 85 4 times, leaving a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 76 from 85 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 19

Let's proceed to step 3:
When dividing 91 by 19, we get 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 76 from 91, we get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 19

Moving on to step 4:
19 can be fit into 155 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
Subtracting 152 from 155 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 19

Moving on to step 5:
If we divide 33 by 19, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 4481.0
The remainder is 14 after subtracting 19 from 33.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 19

On to step 6:
If we divide 141 by 19, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 44817.0
Subtracting 133 from 141 leaves us 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 7:
When dividing 80 by 19, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 44817.4
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 44817.42
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 19, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 44817.421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
When dividing 10 by 19, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 44817.421
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
19 goes into 100 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 44817.42105
Deduct 95 from 100 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
When dividing 50 by 19, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 44817.421052
If we take 38 away from 50, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
When dividing 120 by 19, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 44817.4210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 19, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 44817.42105263
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 44817.42105263 and a remainder of 3e-09.
