79458888 ÷ 687 
We're looking to find how many times 687 goes into 79458888.

Advancing to step 1:
When dividing 7 by 687, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 687

Moving on to step 2:
If we divide 79 by 687, we get 0 and a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 687

Advancing to step 3:
When dividing 794 by 687, we get 1 with a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 687 from 794 leaves us with 107.
Fetch the next digit (5) from the dividend, attach it to 107 and continue: 1075 / 687

Step 4:
The number 687 fits into 1075 1 times, leaving a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 687 from 1075 and we're left with 388.
Append the next digit (8) from the dividend to 388 and continue with: 3888 / 687

Advancing to step 5:
687 can be fit into 3888 5 times, resulting in a remainder of 453.
Write down 5 as next digit of the result. 
Result so far: 115.0
The remainder is 453 after subtracting 3435 from 3888.
Take the next digit (8) from the dividend and append it to 453, then repeat: 4538 / 687

Moving on to step 6:
4538 divided by 687 is 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 1156.0
If we subtract 4122 from 4538, we get 416.
Take the next digit (8) from the dividend and append it to 416, then repeat: 4168 / 687

Moving on to step 7:
When dividing 4168 by 687, we get 6 with a remainder of 46.
The next digit of our result is 6. 
Result so far: 11566.0
Deduct 4122 from 4168 and we're left with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 687

Advancing to step 8:
687 goes into 468 0 times with a remainder of 468.
Use 0 as the next digit of our solution. 
Result so far: 115660.0
Subtracting 0 from 468 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 9:
The number 687 fits into 4680 6 times, leaving a remainder of 558.
The number 6 becomes the next digit in our result. 
Result so far: 115660.6
Deduct 4122 from 4680 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 10:
When dividing 5580 by 687, we get 8 with a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 115660.68
If we subtract 5496 from 5580, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
When dividing 840 by 687, we get 1 with a remainder of 153.
The next digit of our result is 1. 
Result so far: 115660.681
Subtract 687 from 840 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 12:
687 can be fit into 1530 2 times, resulting in a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 115660.6812
Deduct 1374 from 1530 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
687 can be fit into 1560 2 times, resulting in a remainder of 186.
Record the quotient 2 as the next digit in the result. 
Result so far: 115660.68122
The remainder is 186 after subtracting 1374 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final outcome is 115660.68122, with a leftover of 0.000186.
