310521 ÷ 69 
We're looking to find how many times 69 goes into 310521.

On to step 1:
69 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 69

On to step 2:
When dividing 31 by 69, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 69

Step 3:
69 can be fit into 310 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 34 after subtracting 276 from 310.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 69

Step 4:
The number 69 fits into 345 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 345 from 345 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 69

Let's proceed to step 5:
When dividing 2 by 69, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 450.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 69

Let's proceed to step 6:
If we divide 21 by 69, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 4500.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
If we divide 210 by 69, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 4500.3
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
69 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 4500.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
69 can be fit into 300 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4500.304
Deduct 276 from 300 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
69 can be fit into 240 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 4500.3043
If we subtract 207 from 240, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
If we divide 330 by 69, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4500.30434
Subtract 276 from 330 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
The number 69 fits into 540 7 times, leaving a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 4500.304347
Subtract 483 from 540 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
570 divided by 69 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 4500.3043478
Subtract 552 from 570 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
The number 69 fits into 180 2 times, leaving a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 4500.30434782
The remainder is 42 after subtracting 138 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 4500.30434782, with a leftover of 4.2e-08.
