We're dividing 83407553 by 70 
We want to figure out the number of times 83407553 can be divided by 70.

Going ahead to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 70

Moving on to step 2:
83 divided by 70 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 70 from 83 and we're left with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 70

On to step 3:
134 divided by 70 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 70 from 134 to get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 70

Advancing to step 4:
If we divide 640 by 70, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 119.0
If we take 630 away from 640, we end up with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 70

Moving on to step 5:
70 goes into 107 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1191.0
If we subtract 70 from 107, we get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 70

Let's proceed to step 6:
70 can be fit into 375 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 11915.0
The remainder is 25 after subtracting 350 from 375.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 70

Moving on to step 7:
255 divided by 70 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 119153.0
Subtract 210 from 255 to get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 70

Advancing to step 8:
If we divide 453 by 70, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 1191536.0
If we take 420 away from 453, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
If we divide 330 by 70, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 1191536.4
The remainder is 50 after subtracting 280 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
70 goes into 500 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 1191536.47
The remainder is 10 after subtracting 490 from 500.
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 11:
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: 1191536.471
If we take 70 away from 100, we end up 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.

Step 12:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1191536.4714
Subtracting 280 from 300 leaves us 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.

Advancing to step 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1191536.47142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
600 divided by 70 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 1191536.471428
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.

Advancing to step 15:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1191536.4714285
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1191536.47142857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 1191536.47142857 with a remainder of 1e-08.
