We look at the division of 15778045 by 749 
We want to figure out the number of times 15778045 can be divided by 749.

Going ahead to step 1:
749 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 749

Going ahead to step 2:
If we divide 15 by 749, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 749

Moving on to step 3:
157 divided by 749 is 0 with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Include the next digit (7) from the dividend after 157, then repeat: 1577 / 749

Let's proceed to step 4:
When dividing 1577 by 749, we get 2 with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1498 from 1577, we get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 749

Let's proceed to step 5:
749 goes into 798 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 749 from 798 and we're left with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 749

Step 6:
If we divide 490 by 749, we get 0 and a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
If we subtract 0 from 490, we get 490.
Take the next digit (4) from the dividend and append it to 490, then repeat: 4904 / 749

Advancing to step 7:
If we divide 4904 by 749, we get 6 and a remainder of 410.
Record the quotient 6 as the next digit in the result. 
Result so far: 2106.0
The remainder is 410 after subtracting 4494 from 4904.
Include the next digit (5) from the dividend after 410, then repeat: 4105 / 749

Moving on to step 8:
749 can be fit into 4105 5 times, resulting in a remainder of 360.
Put 5 as the next digit of the answer. 
Result so far: 21065.0
Subtract 3745 from 4105 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 9:
If we divide 3600 by 749, we get 4 and a remainder of 604.
Put 4 as the next digit of the answer. 
Result so far: 21065.4
Subtract 2996 from 3600 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 10:
When dividing 6040 by 749, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 21065.48
If we subtract 5992 from 6040, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
When dividing 480 by 749, we get 0 with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 21065.48
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 12:
When dividing 4800 by 749, we get 6 with a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 21065.4806
The remainder is 306 after subtracting 4494 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 13:
749 can be fit into 3060 4 times, resulting in a remainder of 64.
The next digit of our result is 4. 
Result so far: 21065.48064
If we take 2996 away from 3060, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
When dividing 640 by 749, we get 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 21065.48064
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
When dividing 6400 by 749, we get 8 with a remainder of 408.
The next digit of our result is 8. 
Result so far: 21065.4806408
If we subtract 5992 from 6400, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 16:
If we divide 4080 by 749, we get 5 and a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 21065.48064085
Subtracting 3745 from 4080 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final result is 21065.48064085 with a remainder of 3.35e-07.
