73125846 ÷ 87 
Our goal is to divide 73125846 by 87.

On to step 1:
87 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 87

Let's proceed to step 2:
The number 87 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 87

Going ahead to step 3:
87 can be fit into 731 8 times, resulting in a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 696 from 731 and we're left with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 87

Step 4:
352 divided by 87 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we take 348 away from 352, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 87

Advancing to step 5:
45 divided by 87 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 840.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 87

Step 6:
458 divided by 87 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 8405.0
If we take 435 away from 458, we end up with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 87

Advancing to step 7:
87 can be fit into 234 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 84052.0
If we subtract 174 from 234, we get 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 87

Step 8:
87 can be fit into 606 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 840526.0
If we take 522 away from 606, we end up 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.

Step 9:
840 divided by 87 is 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 840526.9
Subtracting 783 from 840 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
The number 87 fits into 570 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 840526.96
If we take 522 away from 570, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 840526.965
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
If we divide 450 by 87, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 840526.9655
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 840526.9655 with a balance of 0.00015.
