We divide 31205397 by 428
Let's see how many times 428 fits into 31205397.

Step 1:
The number 428 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 428

Going ahead to step 2:
31 divided by 428 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 428

On to step 3:
428 can be fit into 312 0 times, resulting in a remainder of 312.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 312, we end up with 312.
Fetch the next digit (0) from the dividend, attach it to 312 and continue: 3120 / 428

Going ahead to step 4:
The number 428 fits into 3120 7 times, leaving a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 2996 from 3120 and we're left with 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 428

Let's proceed to step 5:
1245 divided by 428 is 2 with a remainder of 389.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 856 from 1245 and we're left with 389.
Bring next digit (3) of the dividend behind the 389 and repeat the process: 3893 / 428

Going ahead to step 6:
3893 divided by 428 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 729.0
Subtracting 3852 from 3893 leaves us with 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 428

On to step 7:
428 goes into 419 0 times with a remainder of 419.
Write down 0 as next digit of the result. 
Result so far: 7290.0
Subtracting 0 from 419 leaves us with 419.
Grab the next digit (7) from the dividend, add it to 419, then carry on: 4197 / 428

Going ahead to step 8:
428 can be fit into 4197 9 times, resulting in a remainder of 345.
Use 9 as the next digit of our solution. 
Result so far: 72909.0
If we take 3852 away from 4197, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 9:
When dividing 3450 by 428, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 72909.8
Subtracting 3424 from 3450 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
The number 428 fits into 260 0 times, leaving a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 72909.8
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
When dividing 2600 by 428, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 72909.806
Subtracting 2568 from 2600 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
If we divide 320 by 428, we get 0 and a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 72909.806
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
When dividing 3200 by 428, we get 7 with a remainder of 204.
Write down 7 as next digit of the result. 
Result so far: 72909.80607
The remainder is 204 after subtracting 2996 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 14:
When dividing 2040 by 428, we get 4 with a remainder of 328.
The next digit of our result is 4. 
Result so far: 72909.806074
Subtract 1712 from 2040 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 15:
The number 428 fits into 3280 7 times, leaving a remainder of 284.
Record the quotient 7 as the next digit in the result. 
Result so far: 72909.8060747
The remainder is 284 after subtracting 2996 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 16:
The number 428 fits into 2840 6 times, leaving a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 72909.80607476
If we subtract 2568 from 2840, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 72909.80607476, with a leftover of 2.72e-07.
