15758745 ÷ 102 
We want to divide 15758745 by 102.

On to step 1:
102 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
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 / 102

On to step 2:
The number 102 fits into 15 0 times, leaving 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.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 102

Let's proceed to step 3:
The number 102 fits into 157 1 times, leaving a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 102 from 157, we get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 102

Let's proceed to step 4:
The number 102 fits into 555 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 510 from 555, we get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 102

Advancing to step 5:
102 goes into 458 4 times with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Deduct 408 from 458 and we're left with 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 102

Moving on to step 6:
When dividing 507 by 102, we get 4 with a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 1544.0
Deduct 408 from 507 and we're left with 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 102

Going ahead to step 7:
The number 102 fits into 994 9 times, leaving a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 15449.0
Deduct 918 from 994 and we're left with 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 102

Going ahead to step 8:
102 goes into 765 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 154497.0
Deduct 714 from 765 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
102 can be fit into 510 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 154497.5
The remainder is 0 after subtracting 510 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
102 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 154497.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
102 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 154497.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 154497.5 with a remainder of 0.0.
