69810831 ÷ 580 
We want to figure out the number of times 69810831 can be divided by 580.

Let's proceed to step 1:
6 divided by 580 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 580

Let's proceed to step 2:
If we divide 69 by 580, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 580

Going ahead to step 3:
580 can be fit into 698 1 times, resulting in a remainder of 118.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 118 after subtracting 580 from 698.
Grab the next digit (1) from the dividend, add it to 118, then carry on: 1181 / 580

Advancing to step 4:
If we divide 1181 by 580, we get 2 and a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1160 from 1181 and we're left with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 580

Moving on to step 5:
The number 580 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (8) from the dividend, add it to 210, then carry on: 2108 / 580

Advancing to step 6:
2108 divided by 580 is 3 with a remainder of 368.
Put 3 as the next digit of the answer. 
Result so far: 1203.0
Subtracting 1740 from 2108 leaves us with 368.
Append the next digit (3) from the dividend to 368 and continue with: 3683 / 580

On to step 7:
3683 divided by 580 is 6 with a remainder of 203.
Use 6 as the next digit of our solution. 
Result so far: 12036.0
Subtracting 3480 from 3683 leaves us with 203.
Take the next digit (1) from the dividend and append it to 203, then repeat: 2031 / 580

Advancing to step 8:
If we divide 2031 by 580, we get 3 and a remainder of 291.
Use 3 as the next digit of our solution. 
Result so far: 120363.0
Subtract 1740 from 2031 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
When dividing 2910 by 580, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 120363.5
Subtracting 2900 from 2910 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 580 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 120363.5
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
The number 580 fits into 1000 1 times, leaving a remainder of 420.
The number 1 becomes the next digit in our result. 
Result so far: 120363.501
If we take 580 away from 1000, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
580 can be fit into 4200 7 times, resulting in a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 120363.5017
Subtracting 4060 from 4200 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
580 goes into 1400 2 times with a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 120363.50172
If we subtract 1160 from 1400, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
If we divide 2400 by 580, we get 4 and a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 120363.501724
If we take 2320 away from 2400, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
If we divide 800 by 580, we get 1 and a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 120363.5017241
If we subtract 580 from 800, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 16:
580 goes into 2200 3 times with a remainder of 460.
Write down 3 as next digit of the result. 
Result so far: 120363.50172413
Subtract 1740 from 2200 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 120363.50172413 with a remainder of 4.6e-07.
