We divide 70379878 by 40
Our goal is to divide 70379878 by 40.

Going ahead to step 1:
40 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 40

Moving on to step 2:
The number 40 fits into 70 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 40 from 70, we get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 40

On to step 3:
40 can be fit into 303 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 280 from 303, we get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 40

Going ahead to step 4:
40 can be fit into 237 5 times, resulting in a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
Deduct 200 from 237 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 40

Going ahead to step 5:
40 can be fit into 379 9 times, resulting in a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 1759.0
Deduct 360 from 379 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 40

On to step 6:
The number 40 fits into 198 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 17594.0
The remainder is 38 after subtracting 160 from 198.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 40

Advancing to step 7:
The number 40 fits into 387 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 175949.0
Deduct 360 from 387 and we're left with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 40

On to step 8:
278 divided by 40 is 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 1759496.0
The remainder is 38 after subtracting 240 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
380 divided by 40 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 1759496.9
Deduct 360 from 380 and we're left 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 10:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1759496.95
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1759496.95
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1759496.95
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1759496.95 with a remainder of 0.0.
