15002100 ÷ 707 
We want to divide 15002100 by 707.

Step 1:
707 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 707

Advancing to step 2:
The number 707 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 707

Let's proceed to step 3:
150 divided by 707 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 150, we end up with 150.
Fetch the next digit (0) from the dividend, attach it to 150 and continue: 1500 / 707

Moving on to step 4:
If we divide 1500 by 707, we get 2 and a remainder of 86.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1414 from 1500 to get 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 707

On to step 5:
If we divide 862 by 707, we get 1 and a remainder of 155.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 707 from 862, we get 155.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 707

Step 6:
If we divide 1551 by 707, we get 2 and a remainder of 137.
Write down 2 as next digit of the result. 
Result so far: 212.0
Subtract 1414 from 1551 to get 137.
Grab the next digit (0) from the dividend, add it to 137, then carry on: 1370 / 707

Going ahead to step 7:
The number 707 fits into 1370 1 times, leaving a remainder of 663.
Write down 1 as next digit of the result. 
Result so far: 2121.0
If we subtract 707 from 1370, we get 663.
Grab the next digit (0) from the dividend, add it to 663, then carry on: 6630 / 707

Step 8:
707 goes into 6630 9 times with a remainder of 267.
Write down 9 as next digit of the result. 
Result so far: 21219.0
Subtracting 6363 from 6630 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 9:
707 goes into 2670 3 times with a remainder of 549.
The number 3 becomes the next digit in our result. 
Result so far: 21219.3
If we subtract 2121 from 2670, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 10:
707 can be fit into 5490 7 times, resulting in a remainder of 541.
Put 7 as the next digit of the answer. 
Result so far: 21219.37
If we subtract 4949 from 5490, we get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 11:
When dividing 5410 by 707, we get 7 with a remainder of 461.
The next digit of our result is 7. 
Result so far: 21219.377
The remainder is 461 after subtracting 4949 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

After the division, we end up with 21219.377 and a remainder of 0.0461.
