We look at the division of 84347921 by 623 
We're looking to find how many times 623 goes into 84347921.

Advancing to step 1:
If we divide 8 by 623, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 623

Moving on to step 2:
If we divide 84 by 623, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 623

Going ahead to step 3:
When dividing 843 by 623, we get 1 with a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 623 away from 843, we end up with 220.
Bring next digit (4) of the dividend behind the 220 and repeat the process: 2204 / 623

On to step 4:
623 can be fit into 2204 3 times, resulting in a remainder of 335.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1869 from 2204 leaves us with 335.
Grab the next digit (7) from the dividend, add it to 335, then carry on: 3357 / 623

Advancing to step 5:
When dividing 3357 by 623, we get 5 with a remainder of 242.
Put 5 as the next digit of the answer. 
Result so far: 135.0
The remainder is 242 after subtracting 3115 from 3357.
Bring next digit (9) of the dividend behind the 242 and repeat the process: 2429 / 623

On to step 6:
623 goes into 2429 3 times with a remainder of 560.
Record the quotient 3 as the next digit in the result. 
Result so far: 1353.0
Subtracting 1869 from 2429 leaves us with 560.
Take the next digit (2) from the dividend and append it to 560, then repeat: 5602 / 623

Advancing to step 7:
623 can be fit into 5602 8 times, resulting in a remainder of 618.
The number 8 becomes the next digit in our result. 
Result so far: 13538.0
If we subtract 4984 from 5602, we get 618.
Take the next digit (1) from the dividend and append it to 618, then repeat: 6181 / 623

Moving on to step 8:
If we divide 6181 by 623, we get 9 and a remainder of 574.
The number 9 becomes the next digit in our result. 
Result so far: 135389.0
Deduct 5607 from 6181 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 9:
When dividing 5740 by 623, we get 9 with a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 135389.9
Deduct 5607 from 5740 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 10:
623 goes into 1330 2 times with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 135389.92
Deduct 1246 from 1330 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
623 goes into 840 1 times with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 135389.921
Subtract 623 from 840 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 12:
2170 divided by 623 is 3 with a remainder of 301.
The number 3 becomes the next digit in our result. 
Result so far: 135389.9213
If we subtract 1869 from 2170, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 13:
When dividing 3010 by 623, we get 4 with a remainder of 518.
The number 4 becomes the next digit in our result. 
Result so far: 135389.92134
If we take 2492 away from 3010, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Step 14:
5180 divided by 623 is 8 with a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 135389.921348
If we take 4984 away from 5180, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 15:
The number 623 fits into 1960 3 times, leaving a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 135389.9213483
Subtracting 1869 from 1960 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 16:
If we divide 910 by 623, we get 1 and a remainder of 287.
The next digit of our result is 1. 
Result so far: 135389.92134831
If we subtract 623 from 910, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

In conclusion, the division gives 135389.92134831 with a balance of 2.87e-07.
