21485490 divided by 712 
Let's see how many times 712 fits into 21485490.

Let's proceed to step 1:
If we divide 2 by 712, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 712

Step 2:
When dividing 21 by 712, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 712

Moving on to step 3:
The number 712 fits into 214 0 times, leaving a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Take the next digit (8) from the dividend and append it to 214, then repeat: 2148 / 712

Advancing to step 4:
If we divide 2148 by 712, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2136 from 2148 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 712

Moving on to step 5:
712 can be fit into 125 0 times, resulting in a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 125, we end up with 125.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 712

Moving on to step 6:
712 can be fit into 1254 1 times, resulting in a remainder of 542.
Put 1 as the next digit of the answer. 
Result so far: 301.0
Subtracting 712 from 1254 leaves us with 542.
Append the next digit (9) from the dividend to 542 and continue with: 5429 / 712

Advancing to step 7:
5429 divided by 712 is 7 with a remainder of 445.
Use 7 as the next digit of our solution. 
Result so far: 3017.0
If we take 4984 away from 5429, we end up with 445.
Grab the next digit (0) from the dividend, add it to 445, then carry on: 4450 / 712

On to step 8:
712 can be fit into 4450 6 times, resulting in a remainder of 178.
The next digit of our result is 6. 
Result so far: 30176.0
Subtracting 4272 from 4450 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 9:
When dividing 1780 by 712, we get 2 with a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 30176.2
The remainder is 356 after subtracting 1424 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 10:
When dividing 3560 by 712, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 30176.25
Subtract 3560 from 3560 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.

Going ahead to step 11:
712 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30176.25
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 12:
0 divided by 712 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30176.25
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 quotient of the division is 30176.25, and the remainder is 0.0.
