79309875 ÷ 680 
We want to divide 79309875 by 680.

Let's proceed to step 1:
If we divide 7 by 680, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 680

Moving on to step 2:
79 divided by 680 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 680

Let's proceed to step 3:
680 can be fit into 793 1 times, resulting in a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 680 from 793 to get 113.
Append the next digit (0) from the dividend to 113 and continue with: 1130 / 680

On to step 4:
If we divide 1130 by 680, we get 1 and a remainder of 450.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 680 from 1130 leaves us with 450.
Take the next digit (9) from the dividend and append it to 450, then repeat: 4509 / 680

On to step 5:
680 goes into 4509 6 times with a remainder of 429.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we take 4080 away from 4509, we end up with 429.
Include the next digit (8) from the dividend after 429, then repeat: 4298 / 680

Moving on to step 6:
If we divide 4298 by 680, we get 6 and a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 1166.0
If we take 4080 away from 4298, we end up with 218.
Append the next digit (7) from the dividend to 218 and continue with: 2187 / 680

Moving on to step 7:
680 can be fit into 2187 3 times, resulting in a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 11663.0
If we subtract 2040 from 2187, we get 147.
Append the next digit (5) from the dividend to 147 and continue with: 1475 / 680

On to step 8:
If we divide 1475 by 680, we get 2 and a remainder of 115.
The next digit of our result is 2. 
Result so far: 116632.0
Subtracting 1360 from 1475 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
1150 divided by 680 is 1 with a remainder of 470.
The number 1 becomes the next digit in our result. 
Result so far: 116632.1
Deduct 680 from 1150 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 10:
If we divide 4700 by 680, we get 6 and a remainder of 620.
The next digit of our result is 6. 
Result so far: 116632.16
Subtract 4080 from 4700 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 11:
When dividing 6200 by 680, we get 9 with a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 116632.169
If we take 6120 away from 6200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
680 can be fit into 800 1 times, resulting in a remainder of 120.
The next digit of our result is 1. 
Result so far: 116632.1691
Deduct 680 from 800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
When dividing 1200 by 680, we get 1 with a remainder of 520.
Use 1 as the next digit of our solution. 
Result so far: 116632.16911
Subtracting 680 from 1200 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final outcome is 116632.16911, with a leftover of 0.00052.
