783121 divided by 79 
We want to figure out the number of times 783121 can be divided by 79.

Moving on to step 1:
79 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 79

Step 2:
79 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 79

Advancing to step 3:
When dividing 783 by 79, we get 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 72 after subtracting 711 from 783.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 79

Advancing to step 4:
If we divide 721 by 79, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 711 from 721 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 79

Step 5:
102 divided by 79 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 991.0
If we take 79 away from 102, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 79

On to step 6:
If we divide 231 by 79, we get 2 and a remainder of 73.
The next digit of our result is 2. 
Result so far: 9912.0
The remainder is 73 after subtracting 158 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
If we divide 730 by 79, we get 9 and a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 9912.9
If we take 711 away from 730, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
The number 79 fits into 190 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9912.92
Deduct 158 from 190 and we're left 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.

Going ahead to step 9:
The number 79 fits into 320 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 9912.924
Subtract 316 from 320 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 79 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9912.924
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
400 divided by 79 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9912.92405
If we take 395 away from 400, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
The number 79 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 9912.92405
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
When dividing 500 by 79, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 9912.9240506
Deduct 474 from 500 and we're left 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.

Step 14:
79 goes into 260 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 9912.92405063
The remainder is 23 after subtracting 237 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 9912.92405063 with a remaining 2.3e-08.
