31251738 ÷ 419 
Our goal is to divide 31251738 by 419.

Going ahead to step 1:
3 divided by 419 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 419

Moving on to step 2:
The number 419 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 419

Let's proceed to step 3:
When dividing 312 by 419, we get 0 with a remainder of 312.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 312 leaves us with 312.
Grab the next digit (5) from the dividend, add it to 312, then carry on: 3125 / 419

Moving on to step 4:
If we divide 3125 by 419, we get 7 and a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 2933 from 3125 to get 192.
Take the next digit (1) from the dividend and append it to 192, then repeat: 1921 / 419

Going ahead to step 5:
The number 419 fits into 1921 4 times, leaving a remainder of 245.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 1676 from 1921 and we're left with 245.
Include the next digit (7) from the dividend after 245, then repeat: 2457 / 419

Let's proceed to step 6:
419 goes into 2457 5 times with a remainder of 362.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
If we take 2095 away from 2457, we end up with 362.
Append the next digit (3) from the dividend to 362 and continue with: 3623 / 419

Let's proceed to step 7:
The number 419 fits into 3623 8 times, leaving a remainder of 271.
Put 8 as the next digit of the answer. 
Result so far: 7458.0
Deduct 3352 from 3623 and we're left with 271.
Grab the next digit (8) from the dividend, add it to 271, then carry on: 2718 / 419

Advancing to step 8:
2718 divided by 419 is 6 with a remainder of 204.
The next digit of our result is 6. 
Result so far: 74586.0
If we subtract 2514 from 2718, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 9:
The number 419 fits into 2040 4 times, leaving a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 74586.4
Subtracting 1676 from 2040 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 10:
419 can be fit into 3640 8 times, resulting in a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 74586.48
The remainder is 288 after subtracting 3352 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 11:
419 can be fit into 2880 6 times, resulting in a remainder of 366.
Use 6 as the next digit of our solution. 
Result so far: 74586.486
If we subtract 2514 from 2880, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 12:
419 can be fit into 3660 8 times, resulting in a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 74586.4868
If we take 3352 away from 3660, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 13:
If we divide 3080 by 419, we get 7 and a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 74586.48687
Deduct 2933 from 3080 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 14:
1470 divided by 419 is 3 with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 74586.486873
Deduct 1257 from 1470 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 15:
The number 419 fits into 2130 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 74586.4868735
Deduct 2095 from 2130 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 16:
The number 419 fits into 350 0 times, leaving a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 74586.4868735
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final result is 74586.4868735 with a remainder of 3.5e-07.
