Let's divide 21307101 by 470
We want to figure out the number of times 21307101 can be divided by 470.

Let's proceed to step 1:
470 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 470

On to step 2:
The number 470 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 470

Advancing to step 3:
213 divided by 470 is 0 with a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Bring next digit (0) of the dividend behind the 213 and repeat the process: 2130 / 470

Advancing to step 4:
470 can be fit into 2130 4 times, resulting in a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 250 after subtracting 1880 from 2130.
Fetch the next digit (7) from the dividend, attach it to 250 and continue: 2507 / 470

Moving on to step 5:
When dividing 2507 by 470, we get 5 with a remainder of 157.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 2350 from 2507 leaves us with 157.
Append the next digit (1) from the dividend to 157 and continue with: 1571 / 470

On to step 6:
If we divide 1571 by 470, we get 3 and a remainder of 161.
Write down 3 as next digit of the result. 
Result so far: 453.0
Deduct 1410 from 1571 and we're left with 161.
Bring next digit (0) of the dividend behind the 161 and repeat the process: 1610 / 470

Moving on to step 7:
When dividing 1610 by 470, we get 3 with a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 4533.0
If we subtract 1410 from 1610, we get 200.
Take the next digit (1) from the dividend and append it to 200, then repeat: 2001 / 470

Advancing to step 8:
470 can be fit into 2001 4 times, resulting in a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 45334.0
If we take 1880 away from 2001, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 9:
470 can be fit into 1210 2 times, resulting in a remainder of 270.
Put 2 as the next digit of the answer. 
Result so far: 45334.2
The remainder is 270 after subtracting 940 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
The number 470 fits into 2700 5 times, leaving a remainder of 350.
The next digit of our result is 5. 
Result so far: 45334.25
If we take 2350 away from 2700, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
The number 470 fits into 3500 7 times, leaving a remainder of 210.
Put 7 as the next digit of the answer. 
Result so far: 45334.257
Subtract 3290 from 3500 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
If we divide 2100 by 470, we get 4 and a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 45334.2574
Deduct 1880 from 2100 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
If we divide 2200 by 470, we get 4 and a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 45334.25744
If we take 1880 away from 2200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 45334.25744 with a remaining 0.00032.
