We divide 70687566 by 391
We want to divide 70687566 by 391.

Advancing to step 1:
7 divided by 391 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 391

Moving on to step 2:
If we divide 70 by 391, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 391

Going ahead to step 3:
391 goes into 706 1 times with a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 391 from 706 to get 315.
Append the next digit (8) from the dividend to 315 and continue with: 3158 / 391

On to step 4:
When dividing 3158 by 391, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 3128 from 3158 leaves us with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 391

Going ahead to step 5:
391 can be fit into 307 0 times, resulting in a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 180.0
The remainder is 307 after subtracting 0 from 307.
Fetch the next digit (5) from the dividend, attach it to 307 and continue: 3075 / 391

Step 6:
When dividing 3075 by 391, we get 7 with a remainder of 338.
Write down 7 as next digit of the result. 
Result so far: 1807.0
If we subtract 2737 from 3075, we get 338.
Take the next digit (6) from the dividend and append it to 338, then repeat: 3386 / 391

Advancing to step 7:
391 goes into 3386 8 times with a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 18078.0
Subtracting 3128 from 3386 leaves us with 258.
Append the next digit (6) from the dividend to 258 and continue with: 2586 / 391

Step 8:
391 goes into 2586 6 times with a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 180786.0
Subtracting 2346 from 2586 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 9:
When dividing 2400 by 391, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 180786.6
If we subtract 2346 from 2400, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
391 goes into 540 1 times with a remainder of 149.
Record the quotient 1 as the next digit in the result. 
Result so far: 180786.61
Subtracting 391 from 540 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 11:
391 can be fit into 1490 3 times, resulting in a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 180786.613
Subtract 1173 from 1490 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 12:
The number 391 fits into 3170 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 180786.6138
Subtract 3128 from 3170 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
391 goes into 420 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 180786.61381
The remainder is 29 after subtracting 391 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
391 goes into 290 0 times with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 180786.61381
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 15:
391 can be fit into 2900 7 times, resulting in a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 180786.6138107
Subtracting 2737 from 2900 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 16:
1630 divided by 391 is 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 180786.61381074
Subtracting 1564 from 1630 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.

The final result is 180786.61381074 with a remainder of 6.6e-08.
