We look at the division of 15390380 by 970 
We want to figure out the number of times 15390380 can be divided by 970.

Going ahead to step 1:
1 divided by 970 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 (5) from the dividend to 1 and continue with: 15 / 970

On to step 2:
970 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 970

Going ahead to step 3:
When dividing 153 by 970, we get 0 with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Bring next digit (9) of the dividend behind the 153 and repeat the process: 1539 / 970

Let's proceed to step 4:
970 can be fit into 1539 1 times, resulting in a remainder of 569.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 970 from 1539 leaves us with 569.
Grab the next digit (0) from the dividend, add it to 569, then carry on: 5690 / 970

Step 5:
5690 divided by 970 is 5 with a remainder of 840.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 4850 from 5690 leaves us with 840.
Fetch the next digit (3) from the dividend, attach it to 840 and continue: 8403 / 970

Moving on to step 6:
If we divide 8403 by 970, we get 8 and a remainder of 643.
The next digit of our result is 8. 
Result so far: 158.0
If we subtract 7760 from 8403, we get 643.
Take the next digit (8) from the dividend and append it to 643, then repeat: 6438 / 970

Step 7:
When dividing 6438 by 970, we get 6 with a remainder of 618.
The next digit of our result is 6. 
Result so far: 1586.0
Subtracting 5820 from 6438 leaves us with 618.
Append the next digit (0) from the dividend to 618 and continue with: 6180 / 970

Advancing to step 8:
The number 970 fits into 6180 6 times, leaving a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 15866.0
The remainder is 360 after subtracting 5820 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 9:
The number 970 fits into 3600 3 times, leaving a remainder of 690.
Put 3 as the next digit of the answer. 
Result so far: 15866.3
Deduct 2910 from 3600 and we're left with 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 10:
If we divide 6900 by 970, we get 7 and a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 15866.37
Subtracting 6790 from 6900 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
If we divide 1100 by 970, we get 1 and a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 15866.371
If we take 970 away from 1100, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
If we divide 1300 by 970, we get 1 and a remainder of 330.
Use 1 as the next digit of our solution. 
Result so far: 15866.3711
Subtract 970 from 1300 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The quotient of the division is 15866.3711, and the remainder is 0.0033.
