69866746 divided by 345 
Our goal is to divide 69866746 by 345.

On to step 1:
6 divided by 345 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 345

Advancing to step 2:
345 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 345

On to step 3:
The number 345 fits into 698 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 690 away from 698, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 345

Step 4:
86 divided by 345 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 345

Moving on to step 5:
The number 345 fits into 866 2 times, leaving a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtract 690 from 866 to get 176.
Take the next digit (7) from the dividend and append it to 176, then repeat: 1767 / 345

Moving on to step 6:
1767 divided by 345 is 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 2025.0
Subtracting 1725 from 1767 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 345

Moving on to step 7:
When dividing 424 by 345, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 20251.0
Subtracting 345 from 424 leaves us with 79.
Bring next digit (6) of the dividend behind the 79 and repeat the process: 796 / 345

On to step 8:
345 goes into 796 2 times with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 202512.0
Subtract 690 from 796 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
The number 345 fits into 1060 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 202512.3
If we take 1035 away from 1060, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
345 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 202512.3
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
The number 345 fits into 2500 7 times, leaving a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 202512.307
If we subtract 2415 from 2500, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 12:
345 can be fit into 850 2 times, resulting in a remainder of 160.
The next digit of our result is 2. 
Result so far: 202512.3072
Deduct 690 from 850 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
345 can be fit into 1600 4 times, resulting in a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 202512.30724
Deduct 1380 from 1600 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
If we divide 2200 by 345, we get 6 and a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 202512.307246
Subtracting 2070 from 2200 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 15:
345 can be fit into 1300 3 times, resulting in a remainder of 265.
Use 3 as the next digit of our solution. 
Result so far: 202512.3072463
The remainder is 265 after subtracting 1035 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 16:
345 can be fit into 2650 7 times, resulting in a remainder of 235.
Put 7 as the next digit of the answer. 
Result so far: 202512.30724637
If we subtract 2415 from 2650, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The quotient of the division is 202512.30724637, and the remainder is 2.35e-07.
