31391748 divided by 439 
We're looking to find how many times 439 goes into 31391748.

Advancing to step 1:
The number 439 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 439

On to step 2:
When dividing 31 by 439, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 439

Moving on to step 3:
439 goes into 313 0 times with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 313 after subtracting 0 from 313.
Include the next digit (9) from the dividend after 313, then repeat: 3139 / 439

On to step 4:
The number 439 fits into 3139 7 times, leaving a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 3073 from 3139 and we're left with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 439

Moving on to step 5:
439 can be fit into 661 1 times, resulting in a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 439 from 661 to get 222.
Take the next digit (7) from the dividend and append it to 222, then repeat: 2227 / 439

On to step 6:
2227 divided by 439 is 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 715.0
Deduct 2195 from 2227 and we're left with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 439

Step 7:
439 goes into 324 0 times with a remainder of 324.
Write down 0 as next digit of the result. 
Result so far: 7150.0
Subtracting 0 from 324 leaves us with 324.
Append the next digit (8) from the dividend to 324 and continue with: 3248 / 439

On to step 8:
The number 439 fits into 3248 7 times, leaving a remainder of 175.
The number 7 becomes the next digit in our result. 
Result so far: 71507.0
If we take 3073 away from 3248, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
439 goes into 1750 3 times with a remainder of 433.
Use 3 as the next digit of our solution. 
Result so far: 71507.3
The remainder is 433 after subtracting 1317 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 10:
The number 439 fits into 4330 9 times, leaving a remainder of 379.
Write down 9 as next digit of the result. 
Result so far: 71507.39
If we subtract 3951 from 4330, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 11:
The number 439 fits into 3790 8 times, leaving a remainder of 278.
The number 8 becomes the next digit in our result. 
Result so far: 71507.398
Deduct 3512 from 3790 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 12:
439 can be fit into 2780 6 times, resulting in a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 71507.3986
If we subtract 2634 from 2780, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 13:
439 goes into 1460 3 times with a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 71507.39863
Subtract 1317 from 1460 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 14:
439 goes into 1430 3 times with a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 71507.398633
Deduct 1317 from 1430 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

After the division, we end up with 71507.398633 and a remainder of 1.13e-05.
