67809435 divided by 859 
We want to figure out the number of times 67809435 can be divided by 859.

Step 1:
859 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 859

Advancing to step 2:
859 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 859

Going ahead to step 3:
678 divided by 859 is 0 with a remainder of 678.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 678 and we're left with 678.
Grab the next digit (0) from the dividend, add it to 678, then carry on: 6780 / 859

Advancing to step 4:
When dividing 6780 by 859, we get 7 with a remainder of 767.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 767 after subtracting 6013 from 6780.
Grab the next digit (9) from the dividend, add it to 767, then carry on: 7679 / 859

Step 5:
When dividing 7679 by 859, we get 8 with a remainder of 807.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 6872 from 7679 to get 807.
Take the next digit (4) from the dividend and append it to 807, then repeat: 8074 / 859

Advancing to step 6:
The number 859 fits into 8074 9 times, leaving a remainder of 343.
The number 9 becomes the next digit in our result. 
Result so far: 789.0
The remainder is 343 after subtracting 7731 from 8074.
Bring next digit (3) of the dividend behind the 343 and repeat the process: 3433 / 859

Advancing to step 7:
When dividing 3433 by 859, we get 3 with a remainder of 856.
Record the quotient 3 as the next digit in the result. 
Result so far: 7893.0
Deduct 2577 from 3433 and we're left with 856.
Fetch the next digit (5) from the dividend, attach it to 856 and continue: 8565 / 859

Moving on to step 8:
When dividing 8565 by 859, we get 9 with a remainder of 834.
Write down 9 as next digit of the result. 
Result so far: 78939.0
Deduct 7731 from 8565 and we're left with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 9:
8340 divided by 859 is 9 with a remainder of 609.
The next digit of our result is 9. 
Result so far: 78939.9
If we take 7731 away from 8340, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Step 10:
The number 859 fits into 6090 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 78939.97
Subtract 6013 from 6090 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
If we divide 770 by 859, we get 0 and a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 78939.97
Deduct 0 from 770 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 12:
If we divide 7700 by 859, we get 8 and a remainder of 828.
The next digit of our result is 8. 
Result so far: 78939.9708
The remainder is 828 after subtracting 6872 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Going ahead to step 13:
859 goes into 8280 9 times with a remainder of 549.
Use 9 as the next digit of our solution. 
Result so far: 78939.97089
If we take 7731 away from 8280, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 14:
859 goes into 5490 6 times with a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 78939.970896
Subtract 5154 from 5490 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 15:
859 can be fit into 3360 3 times, resulting in a remainder of 783.
Put 3 as the next digit of the answer. 
Result so far: 78939.9708963
Subtracting 2577 from 3360 leaves us with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Going ahead to step 16:
859 can be fit into 7830 9 times, resulting in a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 78939.97089639
Deduct 7731 from 7830 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

After the division, we end up with 78939.97089639 and a remainder of 9.9e-08.
