31985691 ÷ 759 
We want to divide 31985691 by 759.

Step 1:
If we divide 3 by 759, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 759

Moving on to step 2:
The number 759 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 759

Let's proceed to step 3:
The number 759 fits into 319 0 times, leaving a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 319 and we're left with 319.
Grab the next digit (8) from the dividend, add it to 319, then carry on: 3198 / 759

Let's proceed to step 4:
759 goes into 3198 4 times with a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 162 after subtracting 3036 from 3198.
Append the next digit (5) from the dividend to 162 and continue with: 1625 / 759

Advancing to step 5:
759 can be fit into 1625 2 times, resulting in a remainder of 107.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 1518 from 1625 leaves us with 107.
Bring next digit (6) of the dividend behind the 107 and repeat the process: 1076 / 759

Going ahead to step 6:
If we divide 1076 by 759, we get 1 and a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
If we take 759 away from 1076, we end up with 317.
Include the next digit (9) from the dividend after 317, then repeat: 3179 / 759

Advancing to step 7:
3179 divided by 759 is 4 with a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 4214.0
Subtracting 3036 from 3179 leaves us with 143.
Append the next digit (1) from the dividend to 143 and continue with: 1431 / 759

Going ahead to step 8:
If we divide 1431 by 759, we get 1 and a remainder of 672.
The next digit of our result is 1. 
Result so far: 42141.0
If we take 759 away from 1431, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 9:
When dividing 6720 by 759, we get 8 with a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 42141.8
If we subtract 6072 from 6720, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 10:
When dividing 6480 by 759, we get 8 with a remainder of 408.
The number 8 becomes the next digit in our result. 
Result so far: 42141.88
The remainder is 408 after subtracting 6072 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 42141.88, with a leftover of 0.408.
