19769584 ÷ 858 
We want to figure out the number of times 19769584 can be divided by 858.

Advancing to step 1:
If we divide 1 by 858, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 858

Going ahead to step 2:
858 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 858

On to step 3:
197 divided by 858 is 0 with a remainder of 197.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 197, we end up with 197.
Include the next digit (6) from the dividend after 197, then repeat: 1976 / 858

Let's proceed to step 4:
858 goes into 1976 2 times with a remainder of 260.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1716 away from 1976, we end up with 260.
Include the next digit (9) from the dividend after 260, then repeat: 2609 / 858

Going ahead to step 5:
858 goes into 2609 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 2574 from 2609 to get 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 858

Step 6:
858 can be fit into 355 0 times, resulting in a remainder of 355.
The next digit of our result is 0. 
Result so far: 230.0
Subtract 0 from 355 to get 355.
Fetch the next digit (8) from the dividend, attach it to 355 and continue: 3558 / 858

On to step 7:
858 goes into 3558 4 times with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 2304.0
The remainder is 126 after subtracting 3432 from 3558.
Grab the next digit (4) from the dividend, add it to 126, then carry on: 1264 / 858

On to step 8:
When dividing 1264 by 858, we get 1 with a remainder of 406.
Record the quotient 1 as the next digit in the result. 
Result so far: 23041.0
Subtract 858 from 1264 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 9:
858 can be fit into 4060 4 times, resulting in a remainder of 628.
Put 4 as the next digit of the answer. 
Result so far: 23041.4
Deduct 3432 from 4060 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 10:
858 goes into 6280 7 times with a remainder of 274.
The next digit of our result is 7. 
Result so far: 23041.47
Subtract 6006 from 6280 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 11:
2740 divided by 858 is 3 with a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 23041.473
Subtract 2574 from 2740 to get 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 12:
When dividing 1660 by 858, we get 1 with a remainder of 802.
The number 1 becomes the next digit in our result. 
Result so far: 23041.4731
The remainder is 802 after subtracting 858 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Moving on to step 13:
The number 858 fits into 8020 9 times, leaving a remainder of 298.
Put 9 as the next digit of the answer. 
Result so far: 23041.47319
Subtract 7722 from 8020 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 14:
858 can be fit into 2980 3 times, resulting in a remainder of 406.
Put 3 as the next digit of the answer. 
Result so far: 23041.473193
Deduct 2574 from 2980 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 15:
858 can be fit into 4060 4 times, resulting in a remainder of 628.
Put 4 as the next digit of the answer. 
Result so far: 23041.4731934
The remainder is 628 after subtracting 3432 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 16:
The number 858 fits into 6280 7 times, leaving a remainder of 274.
Write down 7 as next digit of the result. 
Result so far: 23041.47319347
Subtracting 6006 from 6280 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The quotient of the division is 23041.47319347, and the remainder is 2.74e-07.
