We look at the division of 19890866 by 746 
Our goal is to divide 19890866 by 746.

Step 1:
1 divided by 746 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 746

Let's proceed to step 2:
When dividing 19 by 746, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 746

Going ahead to step 3:
746 can be fit into 198 0 times, resulting in a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 198 and we're left with 198.
Bring next digit (9) of the dividend behind the 198 and repeat the process: 1989 / 746

Advancing to step 4:
If we divide 1989 by 746, we get 2 and a remainder of 497.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1492 from 1989, we get 497.
Bring next digit (0) of the dividend behind the 497 and repeat the process: 4970 / 746

Moving on to step 5:
746 goes into 4970 6 times with a remainder of 494.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 4476 from 4970 and we're left with 494.
Include the next digit (8) from the dividend after 494, then repeat: 4948 / 746

Advancing to step 6:
When dividing 4948 by 746, we get 6 with a remainder of 472.
The next digit of our result is 6. 
Result so far: 266.0
Subtracting 4476 from 4948 leaves us with 472.
Grab the next digit (6) from the dividend, add it to 472, then carry on: 4726 / 746

Advancing to step 7:
746 can be fit into 4726 6 times, resulting in a remainder of 250.
Put 6 as the next digit of the answer. 
Result so far: 2666.0
If we subtract 4476 from 4726, we get 250.
Include the next digit (6) from the dividend after 250, then repeat: 2506 / 746

Moving on to step 8:
The number 746 fits into 2506 3 times, leaving a remainder of 268.
The next digit of our result is 3. 
Result so far: 26663.0
Subtracting 2238 from 2506 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 9:
The number 746 fits into 2680 3 times, leaving a remainder of 442.
Put 3 as the next digit of the answer. 
Result so far: 26663.3
If we subtract 2238 from 2680, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
If we divide 4420 by 746, we get 5 and a remainder of 690.
Record the quotient 5 as the next digit in the result. 
Result so far: 26663.35
Subtract 3730 from 4420 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 11:
746 can be fit into 6900 9 times, resulting in a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 26663.359
If we subtract 6714 from 6900, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 12:
1860 divided by 746 is 2 with a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 26663.3592
If we take 1492 away from 1860, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 13:
The number 746 fits into 3680 4 times, leaving a remainder of 696.
Put 4 as the next digit of the answer. 
Result so far: 26663.35924
If we subtract 2984 from 3680, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 14:
6960 divided by 746 is 9 with a remainder of 246.
Use 9 as the next digit of our solution. 
Result so far: 26663.359249
If we subtract 6714 from 6960, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 15:
If we divide 2460 by 746, we get 3 and a remainder of 222.
Write down 3 as next digit of the result. 
Result so far: 26663.3592493
Deduct 2238 from 2460 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 16:
746 goes into 2220 2 times with a remainder of 728.
The next digit of our result is 2. 
Result so far: 26663.35924932
Subtracting 1492 from 2220 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

The final outcome is 26663.35924932, with a leftover of 7.28e-07.
