80813937 ÷ 597 
Let's see how many times 597 fits into 80813937.

Step 1:
597 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 597

Let's proceed to step 2:
When dividing 80 by 597, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 597

Going ahead to step 3:
597 can be fit into 808 1 times, resulting in a remainder of 211.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 211 after subtracting 597 from 808.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 597

Moving on to step 4:
2111 divided by 597 is 3 with a remainder of 320.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1791 from 2111 and we're left with 320.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 597

Going ahead to step 5:
When dividing 3203 by 597, we get 5 with a remainder of 218.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 2985 from 3203, we get 218.
Append the next digit (9) from the dividend to 218 and continue with: 2189 / 597

Step 6:
597 goes into 2189 3 times with a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 1353.0
If we take 1791 away from 2189, we end up with 398.
Fetch the next digit (3) from the dividend, attach it to 398 and continue: 3983 / 597

Going ahead to step 7:
597 can be fit into 3983 6 times, resulting in a remainder of 401.
Use 6 as the next digit of our solution. 
Result so far: 13536.0
If we subtract 3582 from 3983, we get 401.
Fetch the next digit (7) from the dividend, attach it to 401 and continue: 4017 / 597

Moving on to step 8:
If we divide 4017 by 597, we get 6 and a remainder of 435.
Put 6 as the next digit of the answer. 
Result so far: 135366.0
The remainder is 435 after subtracting 3582 from 4017.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 9:
When dividing 4350 by 597, we get 7 with a remainder of 171.
Record the quotient 7 as the next digit in the result. 
Result so far: 135366.7
The remainder is 171 after subtracting 4179 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 10:
The number 597 fits into 1710 2 times, leaving a remainder of 516.
The next digit of our result is 2. 
Result so far: 135366.72
If we take 1194 away from 1710, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 11:
597 goes into 5160 8 times with a remainder of 384.
Write down 8 as next digit of the result. 
Result so far: 135366.728
Subtract 4776 from 5160 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
597 goes into 3840 6 times with a remainder of 258.
Record the quotient 6 as the next digit in the result. 
Result so far: 135366.7286
Subtracting 3582 from 3840 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 13:
If we divide 2580 by 597, we get 4 and a remainder of 192.
The next digit of our result is 4. 
Result so far: 135366.72864
If we take 2388 away from 2580, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
The number 597 fits into 1920 3 times, leaving a remainder of 129.
The next digit of our result is 3. 
Result so far: 135366.728643
If we subtract 1791 from 1920, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 15:
If we divide 1290 by 597, we get 2 and a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 135366.7286432
Deduct 1194 from 1290 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 16:
The number 597 fits into 960 1 times, leaving a remainder of 363.
Put 1 as the next digit of the answer. 
Result so far: 135366.72864321
If we take 597 away from 960, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Our division results in 135366.72864321 with a remaining 3.63e-07.
