31901500 ÷ 4 
We're looking to find how many times 4 goes into 31901500.

Moving on to step 1:
4 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 4

On to step 2:
When dividing 31 by 4, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 28 from 31, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

Going ahead to step 3:
4 goes into 39 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtract 36 from 39 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

Moving on to step 4:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
If we subtract 28 from 30, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Step 5:
4 goes into 21 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 7975.0
The remainder is 1 after subtracting 20 from 21.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Going ahead to step 6:
If we divide 15 by 4, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 79753.0
Subtract 12 from 15 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 4

Moving on to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 797537.0
Deduct 28 from 30 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Advancing to step 8:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7975375.0
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7975375.0
If we subtract 0 from 0, we get 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 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7975375.0
If we subtract 0 from 0, we get 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 quotient of the division is 7975375.0, and the remainder is 0.0.
