83157840 ÷ 591 
We want to figure out the number of times 83157840 can be divided by 591.

Going ahead to step 1:
8 divided by 591 is 0 with 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.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 591

Step 2:
591 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 591

Step 3:
591 goes into 831 1 times with a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 591 away from 831, we end up with 240.
Append the next digit (5) from the dividend to 240 and continue with: 2405 / 591

Let's proceed to step 4:
591 can be fit into 2405 4 times, resulting in a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2364 from 2405, we get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 591

Step 5:
If we divide 417 by 591, we get 0 and a remainder of 417.
Write down 0 as next digit of the result. 
Result so far: 140.0
The remainder is 417 after subtracting 0 from 417.
Take the next digit (8) from the dividend and append it to 417, then repeat: 4178 / 591

On to step 6:
591 goes into 4178 7 times with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 1407.0
The remainder is 41 after subtracting 4137 from 4178.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 591

Advancing to step 7:
The number 591 fits into 414 0 times, leaving a remainder of 414.
The next digit of our result is 0. 
Result so far: 14070.0
If we subtract 0 from 414, we get 414.
Fetch the next digit (0) from the dividend, attach it to 414 and continue: 4140 / 591

Advancing to step 8:
When dividing 4140 by 591, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 140707.0
If we subtract 4137 from 4140, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 591, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 140707.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
591 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 140707.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 140707.0 with a remaining 0.3.
