630989 ÷ 83 
We want to figure out the number of times 630989 can be divided by 83.

On to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 83

On to step 2:
When dividing 63 by 83, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 83

Advancing to step 3:
83 goes into 630 7 times with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 581 away from 630, we end up with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 83

Advancing to step 4:
If we divide 499 by 83, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Deduct 498 from 499 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 83

Step 5:
83 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 760.0
Subtract 0 from 18 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 83

Going ahead to step 6:
When dividing 189 by 83, we get 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 7602.0
The remainder is 23 after subtracting 166 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 83 fits into 230 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 7602.2
Deduct 166 from 230 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
83 can be fit into 640 7 times, resulting in a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7602.27
If we subtract 581 from 640, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
83 can be fit into 590 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7602.277
If we take 581 away from 590, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 7602.277, with a leftover of 0.0009.
