17712339 ÷ 939 
We want to figure out the number of times 17712339 can be divided by 939.

Advancing to step 1:
If we divide 1 by 939, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 939

Advancing to step 2:
939 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 939

Moving on to step 3:
If we divide 177 by 939, we get 0 and a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 177 leaves us with 177.
Take the next digit (1) from the dividend and append it to 177, then repeat: 1771 / 939

Moving on to step 4:
When dividing 1771 by 939, we get 1 with a remainder of 832.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 939 away from 1771, we end up with 832.
Include the next digit (2) from the dividend after 832, then repeat: 8322 / 939

Advancing to step 5:
939 can be fit into 8322 8 times, resulting in a remainder of 810.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 7512 from 8322 leaves us with 810.
Include the next digit (3) from the dividend after 810, then repeat: 8103 / 939

Step 6:
939 goes into 8103 8 times with a remainder of 591.
Write down 8 as next digit of the result. 
Result so far: 188.0
Subtracting 7512 from 8103 leaves us with 591.
Take the next digit (3) from the dividend and append it to 591, then repeat: 5913 / 939

Moving on to step 7:
When dividing 5913 by 939, we get 6 with a remainder of 279.
Put 6 as the next digit of the answer. 
Result so far: 1886.0
Subtract 5634 from 5913 to get 279.
Grab the next digit (9) from the dividend, add it to 279, then carry on: 2799 / 939

Moving on to step 8:
939 can be fit into 2799 2 times, resulting in a remainder of 921.
Use 2 as the next digit of our solution. 
Result so far: 18862.0
Deduct 1878 from 2799 and we're left with 921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9210, and continue the process.

Let's proceed to step 9:
If we divide 9210 by 939, we get 9 and a remainder of 759.
The next digit of our result is 9. 
Result so far: 18862.9
The remainder is 759 after subtracting 8451 from 9210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Advancing to step 10:
939 goes into 7590 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 18862.98
Subtract 7512 from 7590 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
939 can be fit into 780 0 times, resulting in a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 18862.98
If we take 0 away from 780, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 12:
939 can be fit into 7800 8 times, resulting in a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 18862.9808
Subtract 7512 from 7800 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 13:
When dividing 2880 by 939, we get 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 18862.98083
If we subtract 2817 from 2880, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
The number 939 fits into 630 0 times, leaving a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 18862.98083
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 15:
939 goes into 6300 6 times with a remainder of 666.
Put 6 as the next digit of the answer. 
Result so far: 18862.9808306
The remainder is 666 after subtracting 5634 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Step 16:
939 goes into 6660 7 times with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 18862.98083067
If we take 6573 away from 6660, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The quotient of the division is 18862.98083067, and the remainder is 8.7e-08.
