We look at the division of 70742621 by 78 
We want to figure out the number of times 70742621 can be divided by 78.

Going ahead to step 1:
7 divided by 78 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 78

Let's proceed to step 2:
The number 78 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 78

Let's proceed to step 3:
The number 78 fits into 707 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 702 from 707 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 78

Advancing to step 4:
78 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 78

Moving on to step 5:
When dividing 542 by 78, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 906.0
If we subtract 468 from 542, we get 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 78

Advancing to step 6:
If we divide 746 by 78, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 9069.0
If we subtract 702 from 746, we get 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 78

Going ahead to step 7:
78 goes into 442 5 times with a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 90695.0
Deduct 390 from 442 and we're left with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 78

Going ahead to step 8:
521 divided by 78 is 6 with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 906956.0
Subtract 468 from 521 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
If we divide 530 by 78, we get 6 and a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 906956.6
Subtracting 468 from 530 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 906956.67
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
When dividing 740 by 78, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 906956.679
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
78 goes into 380 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 906956.6794
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 13:
If we divide 680 by 78, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 906956.67948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
78 goes into 560 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 906956.679487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
140 divided by 78 is 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 906956.6794871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 16:
When dividing 620 by 78, we get 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 906956.67948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 906956.67948717, and the remainder is 7.4e-08.
