Let's divide 151239 by 73
We're looking to find how many times 73 goes into 151239.

Going ahead to step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 73

Going ahead to step 2:
If we divide 15 by 73, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 73

Step 3:
73 goes into 151 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 146 from 151 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 73

Going ahead to step 4:
73 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 52 after subtracting 0 from 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 73

Step 5:
If we divide 523 by 73, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Deduct 511 from 523 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 73

Moving on to step 6:
73 can be fit into 129 1 times, resulting in a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 2071.0
The remainder is 56 after subtracting 73 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
If we divide 560 by 73, we get 7 and a remainder of 49.
The next digit of our result is 7. 
Result so far: 2071.7
If we take 511 away from 560, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
When dividing 490 by 73, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 2071.76
The remainder is 52 after subtracting 438 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
73 goes into 520 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 2071.767
The remainder is 9 after subtracting 511 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
73 can be fit into 90 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 2071.7671
Deduct 73 from 90 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
When dividing 170 by 73, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2071.76712
If we subtract 146 from 170, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 73, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2071.767123
If we subtract 219 from 240, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
210 divided by 73 is 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 2071.7671232
Subtracting 146 from 210 leaves us 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.

Moving on to step 14:
When dividing 640 by 73, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 2071.76712328
The remainder is 56 after subtracting 584 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 2071.76712328, with a leftover of 5.6e-08.
