We're dividing 16743190 by 78 
We want to figure out the number of times 16743190 can be divided by 78.

Advancing to step 1:
1 divided by 78 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 78

Let's proceed to step 2:
78 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 78

Moving on to step 3:
167 divided by 78 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 156 from 167 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 78

Let's proceed to step 4:
If we divide 114 by 78, we get 1 and a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 78 from 114 and we're left with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 78

Let's proceed to step 5:
The number 78 fits into 363 4 times, leaving a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 214.0
The remainder is 51 after subtracting 312 from 363.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 78

Advancing to step 6:
If we divide 511 by 78, we get 6 and a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 2146.0
If we subtract 468 from 511, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 78

Going ahead to step 7:
78 goes into 439 5 times with a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 21465.0
If we take 390 away from 439, we end up with 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 78

Step 8:
The number 78 fits into 490 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 214656.0
Deduct 468 from 490 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 214656.2
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
When dividing 640 by 78, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 214656.28
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
160 divided by 78 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 214656.282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 78, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 214656.282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 214656.28205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 214656.282051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 15:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 214656.2820512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
78 goes into 640 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 214656.28205128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 214656.28205128, with a leftover of 1.6e-08.
