18502121 divided by 945 
We want to figure out the number of times 18502121 can be divided by 945.

Let's proceed to step 1:
If we divide 1 by 945, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 945

On to step 2:
945 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 945

Advancing to step 3:
945 goes into 185 0 times with a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 185 after subtracting 0 from 185.
Grab the next digit (0) from the dividend, add it to 185, then carry on: 1850 / 945

Step 4:
If we divide 1850 by 945, we get 1 and a remainder of 905.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 945 from 1850 leaves us with 905.
Append the next digit (2) from the dividend to 905 and continue with: 9052 / 945

On to step 5:
When dividing 9052 by 945, we get 9 with a remainder of 547.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 547 after subtracting 8505 from 9052.
Append the next digit (1) from the dividend to 547 and continue with: 5471 / 945

Let's proceed to step 6:
The number 945 fits into 5471 5 times, leaving a remainder of 746.
Use 5 as the next digit of our solution. 
Result so far: 195.0
If we subtract 4725 from 5471, we get 746.
Fetch the next digit (2) from the dividend, attach it to 746 and continue: 7462 / 945

Going ahead to step 7:
945 can be fit into 7462 7 times, resulting in a remainder of 847.
Put 7 as the next digit of the answer. 
Result so far: 1957.0
The remainder is 847 after subtracting 6615 from 7462.
Include the next digit (1) from the dividend after 847, then repeat: 8471 / 945

On to step 8:
945 can be fit into 8471 8 times, resulting in a remainder of 911.
Record the quotient 8 as the next digit in the result. 
Result so far: 19578.0
Subtracting 7560 from 8471 leaves us with 911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9110, and continue the process.

Advancing to step 9:
The number 945 fits into 9110 9 times, leaving a remainder of 605.
Put 9 as the next digit of the answer. 
Result so far: 19578.9
If we subtract 8505 from 9110, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 10:
945 can be fit into 6050 6 times, resulting in a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 19578.96
If we take 5670 away from 6050, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
945 can be fit into 3800 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 19578.964
If we subtract 3780 from 3800, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 945 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 19578.964
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
When dividing 2000 by 945, we get 2 with a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 19578.96402
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 14:
When dividing 1100 by 945, we get 1 with a remainder of 155.
Record the quotient 1 as the next digit in the result. 
Result so far: 19578.964021
Deduct 945 from 1100 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 15:
When dividing 1550 by 945, we get 1 with a remainder of 605.
Put 1 as the next digit of the answer. 
Result so far: 19578.9640211
If we take 945 away from 1550, we end up 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.

The quotient of the division is 19578.9640211, and the remainder is 6.05e-06.
