We look at the division of 30015857 by 745 
We want to divide 30015857 by 745.

Step 1:
When dividing 3 by 745, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 745

On to step 2:
30 divided by 745 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 745

On to step 3:
The number 745 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 300, we get 300.
Fetch the next digit (1) from the dividend, attach it to 300 and continue: 3001 / 745

Let's proceed to step 4:
3001 divided by 745 is 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 2980 from 3001 leaves us with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 745

Advancing to step 5:
745 goes into 215 0 times with a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 215, we end up with 215.
Bring next digit (8) of the dividend behind the 215 and repeat the process: 2158 / 745

Moving on to step 6:
When dividing 2158 by 745, we get 2 with a remainder of 668.
Write down 2 as next digit of the result. 
Result so far: 402.0
The remainder is 668 after subtracting 1490 from 2158.
Include the next digit (5) from the dividend after 668, then repeat: 6685 / 745

Let's proceed to step 7:
6685 divided by 745 is 8 with a remainder of 725.
Record the quotient 8 as the next digit in the result. 
Result so far: 4028.0
Subtracting 5960 from 6685 leaves us with 725.
Take the next digit (7) from the dividend and append it to 725, then repeat: 7257 / 745

On to step 8:
7257 divided by 745 is 9 with a remainder of 552.
Record the quotient 9 as the next digit in the result. 
Result so far: 40289.0
If we subtract 6705 from 7257, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
5520 divided by 745 is 7 with a remainder of 305.
Use 7 as the next digit of our solution. 
Result so far: 40289.7
If we take 5215 away from 5520, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 10:
745 can be fit into 3050 4 times, resulting in a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 40289.74
Subtract 2980 from 3050 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
745 goes into 700 0 times with a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 40289.74
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 12:
If we divide 7000 by 745, we get 9 and a remainder of 295.
Write down 9 as next digit of the result. 
Result so far: 40289.7409
Subtracting 6705 from 7000 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 13:
745 can be fit into 2950 3 times, resulting in a remainder of 715.
Write down 3 as next digit of the result. 
Result so far: 40289.74093
Subtracting 2235 from 2950 leaves us with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Advancing to step 14:
When dividing 7150 by 745, we get 9 with a remainder of 445.
The next digit of our result is 9. 
Result so far: 40289.740939
If we subtract 6705 from 7150, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 15:
745 can be fit into 4450 5 times, resulting in a remainder of 725.
The number 5 becomes the next digit in our result. 
Result so far: 40289.7409395
Subtract 3725 from 4450 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 16:
When dividing 7250 by 745, we get 9 with a remainder of 545.
Put 9 as the next digit of the answer. 
Result so far: 40289.74093959
Subtracting 6705 from 7250 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

In conclusion, the division gives 40289.74093959 with a balance of 5.45e-07.
