Let's divide 84387094 by 129
Let's see how many times 129 fits into 84387094.

Moving on to step 1:
If we divide 8 by 129, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 129

Going ahead to step 2:
If we divide 84 by 129, we get 0 and a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 129

On to step 3:
129 can be fit into 843 6 times, resulting in a remainder of 69.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 774 from 843 leaves us with 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 129

Going ahead to step 4:
698 divided by 129 is 5 with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 645 away from 698, we end up with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 129

Advancing to step 5:
The number 129 fits into 537 4 times, leaving a remainder of 21.
The next digit of our result is 4. 
Result so far: 654.0
Subtracting 516 from 537 leaves us with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 129

Going ahead to step 6:
When dividing 210 by 129, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 6541.0
If we take 129 away from 210, we end up with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 129

Step 7:
129 can be fit into 819 6 times, resulting in a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 65416.0
Subtracting 774 from 819 leaves us with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 129

Let's proceed to step 8:
129 can be fit into 454 3 times, resulting in a remainder of 67.
The next digit of our result is 3. 
Result so far: 654163.0
Deduct 387 from 454 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 9:
When dividing 670 by 129, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 654163.5
If we take 645 away from 670, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
The number 129 fits into 250 1 times, leaving a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 654163.51
If we take 129 away from 250, 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.

On to step 11:
129 goes into 1210 9 times with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 654163.519
The remainder is 49 after subtracting 1161 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
129 can be fit into 490 3 times, resulting in a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 654163.5193
Deduct 387 from 490 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 13:
When dividing 1030 by 129, we get 7 with a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 654163.51937
If we subtract 903 from 1030, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 14:
129 goes into 1270 9 times with a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 654163.519379
The remainder is 109 after subtracting 1161 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 15:
When dividing 1090 by 129, we get 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 654163.5193798
The remainder is 58 after subtracting 1032 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 16:
129 can be fit into 580 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 654163.51937984
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 654163.51937984, with a leftover of 6.4e-08.
