We look at the division of 751857 by 19 
We want to figure out the number of times 751857 can be divided by 19.

Moving on to step 1:
19 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 19

Let's proceed to step 2:
19 can be fit into 75 3 times, resulting in a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 57 away from 75, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 19

On to step 3:
When dividing 181 by 19, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 171 from 181 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 19

Step 4:
108 divided by 19 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 395.0
Subtract 95 from 108 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 19

Going ahead to step 5:
19 goes into 135 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 3957.0
Subtracting 133 from 135 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 19

Advancing to step 6:
The number 19 fits into 27 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 39571.0
Subtracting 19 from 27 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:
If we divide 80 by 19, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 39571.4
Subtract 76 from 80 to 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.

Moving on to step 8:
When dividing 40 by 19, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 39571.42
Deduct 38 from 40 and we're left 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.

Moving on to step 9:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 39571.421
Subtracting 19 from 20 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 39571.421
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39571.42105
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.

Moving on to step 12:
19 goes into 50 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 39571.421052
Subtract 38 from 50 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 39571.4210526
Deduct 114 from 120 and we're left with 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.
Write down 3 as next digit of the result. 
Result so far: 39571.42105263
Deduct 57 from 60 and we're left 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 39571.42105263 and a remainder of 3e-09.
