We look at the division of 16603631 by 945 
We want to figure out the number of times 16603631 can be divided by 945.

On to step 1:
945 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 945

On to step 2:
If we divide 16 by 945, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 945

Advancing to step 3:
166 divided by 945 is 0 with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Fetch the next digit (0) from the dividend, attach it to 166 and continue: 1660 / 945

Let's proceed to step 4:
945 goes into 1660 1 times with a remainder of 715.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 945 away from 1660, we end up with 715.
Fetch the next digit (3) from the dividend, attach it to 715 and continue: 7153 / 945

Step 5:
945 goes into 7153 7 times with a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 538 after subtracting 6615 from 7153.
Grab the next digit (6) from the dividend, add it to 538, then carry on: 5386 / 945

Step 6:
945 goes into 5386 5 times with a remainder of 661.
Write down 5 as next digit of the result. 
Result so far: 175.0
If we take 4725 away from 5386, we end up with 661.
Include the next digit (3) from the dividend after 661, then repeat: 6613 / 945

Advancing to step 7:
If we divide 6613 by 945, we get 6 and a remainder of 943.
Write down 6 as next digit of the result. 
Result so far: 1756.0
Deduct 5670 from 6613 and we're left with 943.
Take the next digit (1) from the dividend and append it to 943, then repeat: 9431 / 945

Let's proceed to step 8:
When dividing 9431 by 945, we get 9 with a remainder of 926.
The number 9 becomes the next digit in our result. 
Result so far: 17569.0
Deduct 8505 from 9431 and we're left with 926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

Let's proceed to step 9:
9260 divided by 945 is 9 with a remainder of 755.
Put 9 as the next digit of the answer. 
Result so far: 17569.9
Deduct 8505 from 9260 and we're left with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 10:
If we divide 7550 by 945, we get 7 and a remainder of 935.
Write down 7 as next digit of the result. 
Result so far: 17569.97
If we take 6615 away from 7550, we end up with 935.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9350, and continue the process.

Going ahead to step 11:
945 can be fit into 9350 9 times, resulting in a remainder of 845.
Put 9 as the next digit of the answer. 
Result so far: 17569.979
Subtracting 8505 from 9350 leaves us with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Let's proceed to step 12:
The number 945 fits into 8450 8 times, leaving a remainder of 890.
The number 8 becomes the next digit in our result. 
Result so far: 17569.9798
Subtract 7560 from 8450 to get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Let's proceed to step 13:
945 can be fit into 8900 9 times, resulting in a remainder of 395.
The next digit of our result is 9. 
Result so far: 17569.97989
Subtracting 8505 from 8900 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 14:
945 can be fit into 3950 4 times, resulting in a remainder of 170.
The number 4 becomes the next digit in our result. 
Result so far: 17569.979894
If we subtract 3780 from 3950, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
1700 divided by 945 is 1 with a remainder of 755.
Put 1 as the next digit of the answer. 
Result so far: 17569.9798941
Subtracting 945 from 1700 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Let's proceed to step 16:
7550 divided by 945 is 7 with a remainder of 935.
Put 7 as the next digit of the answer. 
Result so far: 17569.97989417
The remainder is 935 after subtracting 6615 from 7550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9350, and continue the process.

The final outcome is 17569.97989417, with a leftover of 9.35e-07.
