67430790 ÷ 680 
We're looking to find how many times 680 goes into 67430790.

Step 1:
680 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 680

Going ahead to step 2:
680 can be fit into 67 0 times, resulting in a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 680

Going ahead to step 3:
When dividing 674 by 680, we get 0 with a remainder of 674.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 674 leaves us with 674.
Fetch the next digit (3) from the dividend, attach it to 674 and continue: 6743 / 680

Let's proceed to step 4:
When dividing 6743 by 680, we get 9 with a remainder of 623.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 6120 from 6743, we get 623.
Include the next digit (0) from the dividend after 623, then repeat: 6230 / 680

On to step 5:
6230 divided by 680 is 9 with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 6120 from 6230 leaves us with 110.
Fetch the next digit (7) from the dividend, attach it to 110 and continue: 1107 / 680

Moving on to step 6:
The number 680 fits into 1107 1 times, leaving a remainder of 427.
The number 1 becomes the next digit in our result. 
Result so far: 991.0
Subtracting 680 from 1107 leaves us with 427.
Append the next digit (9) from the dividend to 427 and continue with: 4279 / 680

Going ahead to step 7:
The number 680 fits into 4279 6 times, leaving a remainder of 199.
Record the quotient 6 as the next digit in the result. 
Result so far: 9916.0
If we subtract 4080 from 4279, we get 199.
Fetch the next digit (0) from the dividend, attach it to 199 and continue: 1990 / 680

Moving on to step 8:
The number 680 fits into 1990 2 times, leaving a remainder of 630.
Put 2 as the next digit of the answer. 
Result so far: 99162.0
If we take 1360 away from 1990, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 9:
680 can be fit into 6300 9 times, resulting in a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 99162.9
If we take 6120 away from 6300, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
680 can be fit into 1800 2 times, resulting in a remainder of 440.
Use 2 as the next digit of our solution. 
Result so far: 99162.92
Subtract 1360 from 1800 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
680 can be fit into 4400 6 times, resulting in a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 99162.926
Subtract 4080 from 4400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
The number 680 fits into 3200 4 times, leaving a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 99162.9264
Subtract 2720 from 3200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
680 can be fit into 4800 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 99162.92647
If we subtract 4760 from 4800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
If we divide 400 by 680, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 99162.92647
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
The number 680 fits into 4000 5 times, leaving a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 99162.9264705
Deduct 3400 from 4000 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 16:
680 can be fit into 6000 8 times, resulting in a remainder of 560.
Put 8 as the next digit of the answer. 
Result so far: 99162.92647058
Subtract 5440 from 6000 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 99162.92647058, with a leftover of 5.6e-07.
