We're dividing 83711270 by 320 
We want to divide 83711270 by 320.

On to step 1:
If we divide 8 by 320, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 320

Moving on to step 2:
If we divide 83 by 320, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 320

On to step 3:
The number 320 fits into 837 2 times, leaving a remainder of 197.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 640 from 837 leaves us with 197.
Append the next digit (1) from the dividend to 197 and continue with: 1971 / 320

On to step 4:
320 can be fit into 1971 6 times, resulting in a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 1920 from 1971, we get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 320

Moving on to step 5:
When dividing 511 by 320, we get 1 with a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Deduct 320 from 511 and we're left with 191.
Take the next digit (2) from the dividend and append it to 191, then repeat: 1912 / 320

Advancing to step 6:
320 can be fit into 1912 5 times, resulting in a remainder of 312.
Use 5 as the next digit of our solution. 
Result so far: 2615.0
The remainder is 312 after subtracting 1600 from 1912.
Grab the next digit (7) from the dividend, add it to 312, then carry on: 3127 / 320

Let's proceed to step 7:
3127 divided by 320 is 9 with a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 26159.0
Subtract 2880 from 3127 to get 247.
Take the next digit (0) from the dividend and append it to 247, then repeat: 2470 / 320

Advancing to step 8:
320 can be fit into 2470 7 times, resulting in a remainder of 230.
Record the quotient 7 as the next digit in the result. 
Result so far: 261597.0
If we subtract 2240 from 2470, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 9:
320 can be fit into 2300 7 times, resulting in a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 261597.7
Subtracting 2240 from 2300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 320, we get 1 and a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 261597.71
If we subtract 320 from 600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
When dividing 2800 by 320, we get 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 261597.718
Subtract 2560 from 2800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
When dividing 2400 by 320, we get 7 with a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 261597.7187
Subtract 2240 from 2400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 261597.71875
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
320 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 261597.71875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
When dividing 0 by 320, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 261597.71875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 261597.71875, with a leftover of 0.0.
