68220340 ÷ 849 
We want to figure out the number of times 68220340 can be divided by 849.

Going ahead to step 1:
When dividing 6 by 849, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 849

Step 2:
849 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 849

Step 3:
682 divided by 849 is 0 with a remainder of 682.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 682 leaves us with 682.
Take the next digit (2) from the dividend and append it to 682, then repeat: 6822 / 849

On to step 4:
849 goes into 6822 8 times with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6792 from 6822 to get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 849

Moving on to step 5:
The number 849 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 300, we end up with 300.
Fetch the next digit (3) from the dividend, attach it to 300 and continue: 3003 / 849

On to step 6:
When dividing 3003 by 849, we get 3 with a remainder of 456.
Use 3 as the next digit of our solution. 
Result so far: 803.0
If we subtract 2547 from 3003, we get 456.
Append the next digit (4) from the dividend to 456 and continue with: 4564 / 849

On to step 7:
849 goes into 4564 5 times with a remainder of 319.
Write down 5 as next digit of the result. 
Result so far: 8035.0
Deduct 4245 from 4564 and we're left with 319.
Append the next digit (0) from the dividend to 319 and continue with: 3190 / 849

Step 8:
If we divide 3190 by 849, we get 3 and a remainder of 643.
Record the quotient 3 as the next digit in the result. 
Result so far: 80353.0
If we take 2547 away from 3190, we end up with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 9:
If we divide 6430 by 849, we get 7 and a remainder of 487.
Use 7 as the next digit of our solution. 
Result so far: 80353.7
Subtract 5943 from 6430 to get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 10:
When dividing 4870 by 849, we get 5 with a remainder of 625.
The next digit of our result is 5. 
Result so far: 80353.75
The remainder is 625 after subtracting 4245 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 11:
The number 849 fits into 6250 7 times, leaving a remainder of 307.
Use 7 as the next digit of our solution. 
Result so far: 80353.757
Subtract 5943 from 6250 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 12:
When dividing 3070 by 849, we get 3 with a remainder of 523.
The number 3 becomes the next digit in our result. 
Result so far: 80353.7573
If we take 2547 away from 3070, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

On to step 13:
If we divide 5230 by 849, we get 6 and a remainder of 136.
The next digit of our result is 6. 
Result so far: 80353.75736
Subtract 5094 from 5230 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 14:
When dividing 1360 by 849, we get 1 with a remainder of 511.
Put 1 as the next digit of the answer. 
Result so far: 80353.757361
Subtract 849 from 1360 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 15:
849 can be fit into 5110 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 80353.7573616
Deduct 5094 from 5110 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
160 divided by 849 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 80353.7573616
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 80353.7573616 with a remainder of 1.6e-07.
