73187525 divided by 345 
Our goal is to divide 73187525 by 345.

Going ahead to step 1:
When dividing 7 by 345, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 345

Step 2:
345 goes into 73 0 times with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 345

Moving on to step 3:
345 goes into 731 2 times with a remainder of 41.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 690 from 731, we get 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 345

Advancing to step 4:
345 can be fit into 418 1 times, resulting in a remainder of 73.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 345 from 418 to get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 345

Going ahead to step 5:
345 goes into 737 2 times with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 212.0
The remainder is 47 after subtracting 690 from 737.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 345

Let's proceed to step 6:
The number 345 fits into 475 1 times, leaving a remainder of 130.
The next digit of our result is 1. 
Result so far: 2121.0
Subtracting 345 from 475 leaves us with 130.
Fetch the next digit (2) from the dividend, attach it to 130 and continue: 1302 / 345

Advancing to step 7:
The number 345 fits into 1302 3 times, leaving a remainder of 267.
Use 3 as the next digit of our solution. 
Result so far: 21213.0
If we subtract 1035 from 1302, we get 267.
Bring next digit (5) of the dividend behind the 267 and repeat the process: 2675 / 345

Moving on to step 8:
2675 divided by 345 is 7 with a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 212137.0
If we take 2415 away from 2675, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 9:
If we divide 2600 by 345, we get 7 and a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 212137.7
Deduct 2415 from 2600 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 10:
When dividing 1850 by 345, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 212137.75
If we subtract 1725 from 1850, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 11:
If we divide 1250 by 345, we get 3 and a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 212137.753
If we subtract 1035 from 1250, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 12:
345 goes into 2150 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 212137.7536
The remainder is 80 after subtracting 2070 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
345 goes into 800 2 times with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 212137.75362
Subtract 690 from 800 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 14:
The number 345 fits into 1100 3 times, leaving a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 212137.753623
If we subtract 1035 from 1100, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 15:
When dividing 650 by 345, we get 1 with a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 212137.7536231
Deduct 345 from 650 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 16:
The number 345 fits into 3050 8 times, leaving a remainder of 290.
The next digit of our result is 8. 
Result so far: 212137.75362318
If we subtract 2760 from 3050, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 212137.75362318, with a leftover of 2.9e-07.
