We're dividing 2182139 by 623 
We're looking to find how many times 623 goes into 2182139.

Going ahead to step 1:
If we divide 2 by 623, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 623

Going ahead to step 2:
If we divide 21 by 623, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 623

Advancing to step 3:
218 divided by 623 is 0 with a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Grab the next digit (2) from the dividend, add it to 218, then carry on: 2182 / 623

Let's proceed to step 4:
623 goes into 2182 3 times with a remainder of 313.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1869 from 2182 leaves us with 313.
Include the next digit (1) from the dividend after 313, then repeat: 3131 / 623

Moving on to step 5:
The number 623 fits into 3131 5 times, leaving a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 3115 away from 3131, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 623

On to step 6:
The number 623 fits into 163 0 times, leaving a remainder of 163.
Write down 0 as next digit of the result. 
Result so far: 350.0
If we subtract 0 from 163, we get 163.
Grab the next digit (9) from the dividend, add it to 163, then carry on: 1639 / 623

On to step 7:
The number 623 fits into 1639 2 times, leaving a remainder of 393.
Write down 2 as next digit of the result. 
Result so far: 3502.0
If we take 1246 away from 1639, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 8:
When dividing 3930 by 623, we get 6 with a remainder of 192.
The next digit of our result is 6. 
Result so far: 3502.6
The remainder is 192 after subtracting 3738 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
623 can be fit into 1920 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 3502.63
If we subtract 1869 from 1920, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
623 goes into 510 0 times with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 3502.63
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 11:
623 can be fit into 5100 8 times, resulting in a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 3502.6308
If we take 4984 away from 5100, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
623 can be fit into 1160 1 times, resulting in a remainder of 537.
The next digit of our result is 1. 
Result so far: 3502.63081
Subtracting 623 from 1160 leaves us with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 13:
When dividing 5370 by 623, we get 8 with a remainder of 386.
Write down 8 as next digit of the result. 
Result so far: 3502.630818
If we subtract 4984 from 5370, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 14:
The number 623 fits into 3860 6 times, leaving a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 3502.6308186
The remainder is 122 after subtracting 3738 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 15:
When dividing 1220 by 623, we get 1 with a remainder of 597.
Use 1 as the next digit of our solution. 
Result so far: 3502.63081861
Deduct 623 from 1220 and we're left with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

The final outcome is 3502.63081861, with a leftover of 5.97e-07.
