Let's divide 21007212 by 616
We want to divide 21007212 by 616.

Step 1:
When dividing 2 by 616, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 616

On to step 2:
The number 616 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 616

Advancing to step 3:
616 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 616

Step 4:
The number 616 fits into 2100 3 times, leaving a remainder of 252.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1848 away from 2100, we end up with 252.
Take the next digit (7) from the dividend and append it to 252, then repeat: 2527 / 616

Step 5:
2527 divided by 616 is 4 with a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 2464 from 2527 leaves us with 63.
Bring next digit (2) of the dividend behind the 63 and repeat the process: 632 / 616

Going ahead to step 6:
When dividing 632 by 616, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 341.0
The remainder is 16 after subtracting 616 from 632.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 616

Step 7:
If we divide 161 by 616, we get 0 and a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 3410.0
The remainder is 161 after subtracting 0 from 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 616

On to step 8:
616 can be fit into 1612 2 times, resulting in a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 34102.0
Subtract 1232 from 1612 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 9:
3800 divided by 616 is 6 with a remainder of 104.
The next digit of our result is 6. 
Result so far: 34102.6
If we take 3696 away from 3800, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
1040 divided by 616 is 1 with a remainder of 424.
The next digit of our result is 1. 
Result so far: 34102.61
Deduct 616 from 1040 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 11:
When dividing 4240 by 616, we get 6 with a remainder of 544.
The next digit of our result is 6. 
Result so far: 34102.616
Subtract 3696 from 4240 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 12:
5440 divided by 616 is 8 with a remainder of 512.
Put 8 as the next digit of the answer. 
Result so far: 34102.6168
The remainder is 512 after subtracting 4928 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 13:
616 goes into 5120 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 34102.61688
Deduct 4928 from 5120 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 34102.61688, with a leftover of 0.000192.
