69806105 divided by 645 
We want to figure out the number of times 69806105 can be divided by 645.

On to step 1:
If we divide 6 by 645, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 645

Let's proceed to step 2:
69 divided by 645 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 645

Let's proceed to step 3:
When dividing 698 by 645, we get 1 with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 645 from 698 and we're left with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 645

On to step 4:
When dividing 530 by 645, we get 0 with a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 530 after subtracting 0 from 530.
Take the next digit (6) from the dividend and append it to 530, then repeat: 5306 / 645

Let's proceed to step 5:
If we divide 5306 by 645, we get 8 and a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Deduct 5160 from 5306 and we're left with 146.
Take the next digit (1) from the dividend and append it to 146, then repeat: 1461 / 645

Advancing to step 6:
645 can be fit into 1461 2 times, resulting in a remainder of 171.
Write down 2 as next digit of the result. 
Result so far: 1082.0
Deduct 1290 from 1461 and we're left with 171.
Bring next digit (0) of the dividend behind the 171 and repeat the process: 1710 / 645

Going ahead to step 7:
The number 645 fits into 1710 2 times, leaving a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 10822.0
If we subtract 1290 from 1710, we get 420.
Bring next digit (5) of the dividend behind the 420 and repeat the process: 4205 / 645

On to step 8:
If we divide 4205 by 645, we get 6 and a remainder of 335.
The next digit of our result is 6. 
Result so far: 108226.0
Subtract 3870 from 4205 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
645 can be fit into 3350 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 108226.5
If we take 3225 away from 3350, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 10:
The number 645 fits into 1250 1 times, leaving a remainder of 605.
Write down 1 as next digit of the result. 
Result so far: 108226.51
Deduct 645 from 1250 and we're left with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 11:
When dividing 6050 by 645, we get 9 with a remainder of 245.
Put 9 as the next digit of the answer. 
Result so far: 108226.519
The remainder is 245 after subtracting 5805 from 6050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 12:
2450 divided by 645 is 3 with a remainder of 515.
Use 3 as the next digit of our solution. 
Result so far: 108226.5193
Deduct 1935 from 2450 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 13:
When dividing 5150 by 645, we get 7 with a remainder of 635.
The number 7 becomes the next digit in our result. 
Result so far: 108226.51937
Subtract 4515 from 5150 to get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 14:
645 goes into 6350 9 times with a remainder of 545.
Write down 9 as next digit of the result. 
Result so far: 108226.519379
If we take 5805 away from 6350, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 15:
When dividing 5450 by 645, we get 8 with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 108226.5193798
Subtracting 5160 from 5450 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 16:
When dividing 2900 by 645, we get 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 108226.51937984
If we subtract 2580 from 2900, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 108226.51937984 and a remainder of 3.2e-07.
