78746943 ÷ 153 
We want to figure out the number of times 78746943 can be divided by 153.

Going ahead to step 1:
When dividing 7 by 153, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 153

On to step 2:
If we divide 78 by 153, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 153

On to step 3:
The number 153 fits into 787 5 times, leaving a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 765 from 787 to get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 153

Let's proceed to step 4:
153 can be fit into 224 1 times, resulting in a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 153 from 224, we get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 153

On to step 5:
153 goes into 716 4 times with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 514.0
Deduct 612 from 716 and we're left with 104.
Include the next digit (9) from the dividend after 104, then repeat: 1049 / 153

Let's proceed to step 6:
The number 153 fits into 1049 6 times, leaving a remainder of 131.
Use 6 as the next digit of our solution. 
Result so far: 5146.0
If we take 918 away from 1049, we end up with 131.
Take the next digit (4) from the dividend and append it to 131, then repeat: 1314 / 153

On to step 7:
When dividing 1314 by 153, we get 8 with a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 51468.0
Deduct 1224 from 1314 and we're left with 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 153

On to step 8:
903 divided by 153 is 5 with a remainder of 138.
Use 5 as the next digit of our solution. 
Result so far: 514685.0
If we subtract 765 from 903, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 9:
When dividing 1380 by 153, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 514685.9
If we take 1377 away from 1380, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
30 divided by 153 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 514685.9
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 153, we get 1 and a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 514685.901
Subtract 153 from 300 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 12:
153 can be fit into 1470 9 times, resulting in a remainder of 93.
The next digit of our result is 9. 
Result so far: 514685.9019
The remainder is 93 after subtracting 1377 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 13:
153 can be fit into 930 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 514685.90196
Subtracting 918 from 930 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
120 divided by 153 is 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 514685.90196
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
The number 153 fits into 1200 7 times, leaving a remainder of 129.
The next digit of our result is 7. 
Result so far: 514685.9019607
The remainder is 129 after subtracting 1071 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 16:
1290 divided by 153 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 514685.90196078
Subtracting 1224 from 1290 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 514685.90196078 and a remainder of 6.6e-08.
