31848921 divided by 407 
We want to figure out the number of times 31848921 can be divided by 407.

Let's proceed to step 1:
3 divided by 407 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 407

Moving on to step 2:
The number 407 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 407

Let's proceed to step 3:
407 goes into 318 0 times with a remainder of 318.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 318 leaves us with 318.
Grab the next digit (4) from the dividend, add it to 318, then carry on: 3184 / 407

Let's proceed to step 4:
When dividing 3184 by 407, we get 7 with a remainder of 335.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 2849 from 3184 leaves us with 335.
Include the next digit (8) from the dividend after 335, then repeat: 3358 / 407

Going ahead to step 5:
407 can be fit into 3358 8 times, resulting in a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 3256 away from 3358, we end up with 102.
Bring next digit (9) of the dividend behind the 102 and repeat the process: 1029 / 407

Moving on to step 6:
407 can be fit into 1029 2 times, resulting in a remainder of 215.
Use 2 as the next digit of our solution. 
Result so far: 782.0
The remainder is 215 after subtracting 814 from 1029.
Fetch the next digit (2) from the dividend, attach it to 215 and continue: 2152 / 407

Let's proceed to step 7:
If we divide 2152 by 407, we get 5 and a remainder of 117.
Use 5 as the next digit of our solution. 
Result so far: 7825.0
The remainder is 117 after subtracting 2035 from 2152.
Take the next digit (1) from the dividend and append it to 117, then repeat: 1171 / 407

On to step 8:
If we divide 1171 by 407, we get 2 and a remainder of 357.
Write down 2 as next digit of the result. 
Result so far: 78252.0
If we subtract 814 from 1171, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 9:
3570 divided by 407 is 8 with a remainder of 314.
Put 8 as the next digit of the answer. 
Result so far: 78252.8
If we take 3256 away from 3570, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 10:
407 goes into 3140 7 times with a remainder of 291.
Record the quotient 7 as the next digit in the result. 
Result so far: 78252.87
Deduct 2849 from 3140 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 11:
The number 407 fits into 2910 7 times, leaving a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 78252.877
Subtract 2849 from 2910 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 78252.877 with a remaining 0.0061.
