We divide 6435840 by 31
We're looking to find how many times 31 goes into 6435840.

Let's proceed to step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 31

On to step 2:
If we divide 64 by 31, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 62 away from 64, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 31

Going ahead to step 3:
When dividing 23 by 31, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 23, we get 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 31

Moving on to step 4:
31 goes into 235 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
If we subtract 217 from 235, we get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 31

Let's proceed to step 5:
The number 31 fits into 188 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 2076.0
If we subtract 186 from 188, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 31

Step 6:
31 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 20760.0
Subtract 0 from 24 to get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 31

On to step 7:
240 divided by 31 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 207607.0
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 207607.7
If we subtract 217 from 230, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 31 fits into 130 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 207607.74
Deduct 124 from 130 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 31 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 207607.741
Deduct 31 from 60 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
31 can be fit into 290 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 207607.7419
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 207607.74193
Subtracting 93 from 110 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
If we divide 170 by 31, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 207607.741935
Subtract 155 from 170 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 207607.7419354
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 15:
31 can be fit into 260 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 207607.74193548
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 207607.74193548, with a leftover of 1.2e-08.
