We're dividing 21153463 by 627 
We want to divide 21153463 by 627.

Step 1:
627 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the 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 / 627

On to step 2:
21 divided by 627 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 627

Let's proceed to step 3:
The number 627 fits into 211 0 times, leaving a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Take the next digit (5) from the dividend and append it to 211, then repeat: 2115 / 627

On to step 4:
2115 divided by 627 is 3 with a remainder of 234.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1881 away from 2115, we end up with 234.
Grab the next digit (3) from the dividend, add it to 234, then carry on: 2343 / 627

Going ahead to step 5:
When dividing 2343 by 627, we get 3 with a remainder of 462.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 1881 from 2343 and we're left with 462.
Fetch the next digit (4) from the dividend, attach it to 462 and continue: 4624 / 627

Let's proceed to step 6:
4624 divided by 627 is 7 with a remainder of 235.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
Subtract 4389 from 4624 to get 235.
Append the next digit (6) from the dividend to 235 and continue with: 2356 / 627

Advancing to step 7:
When dividing 2356 by 627, we get 3 with a remainder of 475.
Write down 3 as next digit of the result. 
Result so far: 3373.0
Subtract 1881 from 2356 to get 475.
Grab the next digit (3) from the dividend, add it to 475, then carry on: 4753 / 627

Advancing to step 8:
If we divide 4753 by 627, we get 7 and a remainder of 364.
The next digit of our result is 7. 
Result so far: 33737.0
If we subtract 4389 from 4753, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 9:
If we divide 3640 by 627, we get 5 and a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 33737.5
Subtract 3135 from 3640 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 10:
627 can be fit into 5050 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 33737.58
Subtract 5016 from 5050 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
If we divide 340 by 627, we get 0 and a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 33737.58
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
3400 divided by 627 is 5 with a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 33737.5805
If we take 3135 away from 3400, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 13:
When dividing 2650 by 627, we get 4 with a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 33737.58054
If we subtract 2508 from 2650, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 14:
The number 627 fits into 1420 2 times, leaving a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 33737.580542
Deduct 1254 from 1420 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 15:
If we divide 1660 by 627, we get 2 and a remainder of 406.
Record the quotient 2 as the next digit in the result. 
Result so far: 33737.5805422
Deduct 1254 from 1660 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final outcome is 33737.5805422, with a leftover of 4.06e-06.
