Let's divide 77874273 by 70
We want to figure out the number of times 77874273 can be divided by 70.

Let's proceed to step 1:
70 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 70

Moving on to step 2:
When dividing 77 by 70, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 7 after subtracting 70 from 77.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 70

Going ahead to step 3:
When dividing 78 by 70, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 70 from 78, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 70

Step 4:
If we divide 87 by 70, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Deduct 70 from 87 and we're left with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 70

Moving on to step 5:
70 can be fit into 174 2 times, resulting in a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 1112.0
Subtract 140 from 174 to get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 70

Going ahead to step 6:
If we divide 342 by 70, we get 4 and a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 11124.0
If we subtract 280 from 342, we get 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 70

Moving on to step 7:
When dividing 627 by 70, we get 8 with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 111248.0
The remainder is 67 after subtracting 560 from 627.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 70

Step 8:
70 can be fit into 673 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 1112489.0
If we take 630 away from 673, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
The number 70 fits into 430 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1112489.6
Subtract 420 from 430 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.

Going ahead to step 10:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1112489.61
Subtract 70 from 100 to 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.

Let's proceed to step 11:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1112489.614
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 1112489.6142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1112489.61428
Subtract 560 from 600 to 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.

Step 14:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1112489.614285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 15:
If we divide 500 by 70, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1112489.6142857
Subtract 490 from 500 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.

Advancing to step 16:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1112489.61428571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 1112489.61428571, with a leftover of 3e-08.
