Let's divide 81669776 by 87
Our goal is to divide 81669776 by 87.

On to step 1:
87 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 87

On to step 2:
87 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 87

Moving on to step 3:
87 goes into 816 9 times with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 783 from 816 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 87

Advancing to step 4:
336 divided by 87 is 3 with a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 261 away from 336, we end up with 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 87

Let's proceed to step 5:
If we divide 759 by 87, we get 8 and a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 938.0
Subtracting 696 from 759 leaves us with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 87

Step 6:
87 goes into 637 7 times with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 9387.0
If we subtract 609 from 637, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 87

Let's proceed to step 7:
If we divide 287 by 87, we get 3 and a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 93873.0
Deduct 261 from 287 and we're left with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 87

Going ahead to step 8:
87 goes into 266 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 938733.0
The remainder is 5 after subtracting 261 from 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 87 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 938733.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
87 can be fit into 500 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 938733.05
The remainder is 65 after subtracting 435 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
87 can be fit into 650 7 times, resulting in a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 938733.057
Subtract 609 from 650 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 12:
If we divide 410 by 87, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 938733.0574
If we subtract 348 from 410, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
87 can be fit into 620 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 938733.05747
Deduct 609 from 620 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
When dividing 110 by 87, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 938733.057471
If we take 87 away from 110, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
If we divide 230 by 87, we get 2 and a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 938733.0574712
If we subtract 174 from 230, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
87 can be fit into 560 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 938733.05747126
The remainder is 38 after subtracting 522 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 938733.05747126, with a leftover of 3.8e-08.
