We look at the division of 21513460 by 703 
Let's see how many times 703 fits into 21513460.

Advancing to step 1:
If we divide 2 by 703, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 703

Moving on to step 2:
21 divided by 703 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 703

Moving on to step 3:
703 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Bring next digit (1) of the dividend behind the 215 and repeat the process: 2151 / 703

Advancing to step 4:
When dividing 2151 by 703, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2109 from 2151 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 703

Going ahead to step 5:
423 divided by 703 is 0 with a remainder of 423.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 423, we get 423.
Include the next digit (4) from the dividend after 423, then repeat: 4234 / 703

On to step 6:
The number 703 fits into 4234 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 306.0
The remainder is 16 after subtracting 4218 from 4234.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 703

Moving on to step 7:
If we divide 166 by 703, we get 0 and a remainder of 166.
The next digit of our result is 0. 
Result so far: 3060.0
Deduct 0 from 166 and we're left with 166.
Grab the next digit (0) from the dividend, add it to 166, then carry on: 1660 / 703

Moving on to step 8:
703 can be fit into 1660 2 times, resulting in a remainder of 254.
The next digit of our result is 2. 
Result so far: 30602.0
Subtract 1406 from 1660 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 9:
When dividing 2540 by 703, we get 3 with a remainder of 431.
Write down 3 as next digit of the result. 
Result so far: 30602.3
Subtract 2109 from 2540 to get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Going ahead to step 10:
4310 divided by 703 is 6 with a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 30602.36
If we subtract 4218 from 4310, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 11:
The number 703 fits into 920 1 times, leaving a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 30602.361
If we subtract 703 from 920, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 12:
The number 703 fits into 2170 3 times, leaving a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 30602.3613
If we subtract 2109 from 2170, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
The number 703 fits into 610 0 times, leaving a remainder of 610.
The next digit of our result is 0. 
Result so far: 30602.3613
The remainder is 610 after subtracting 0 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 14:
If we divide 6100 by 703, we get 8 and a remainder of 476.
The next digit of our result is 8. 
Result so far: 30602.361308
If we subtract 5624 from 6100, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 15:
703 can be fit into 4760 6 times, resulting in a remainder of 542.
The next digit of our result is 6. 
Result so far: 30602.3613086
Subtract 4218 from 4760 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 16:
When dividing 5420 by 703, we get 7 with a remainder of 499.
Put 7 as the next digit of the answer. 
Result so far: 30602.36130867
Subtract 4921 from 5420 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

The final outcome is 30602.36130867, with a leftover of 4.99e-07.
