We divide 78864694 by 121
We want to divide 78864694 by 121.

Moving on to step 1:
The number 121 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 121

Advancing to step 2:
78 divided by 121 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 121

Step 3:
The number 121 fits into 788 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 6.0
If we take 726 away from 788, we end up with 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 121

Going ahead to step 4:
121 can be fit into 626 5 times, resulting in a remainder of 21.
The next digit of our result is 5. 
Result so far: 65.0
If we take 605 away from 626, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 121

Going ahead to step 5:
The number 121 fits into 214 1 times, leaving a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 651.0
The remainder is 93 after subtracting 121 from 214.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 121

Going ahead to step 6:
121 can be fit into 936 7 times, resulting in a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 6517.0
Subtracting 847 from 936 leaves us with 89.
Bring next digit (9) of the dividend behind the 89 and repeat the process: 899 / 121

Advancing to step 7:
When dividing 899 by 121, we get 7 with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 65177.0
Deduct 847 from 899 and we're left with 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 121

Going ahead to step 8:
If we divide 524 by 121, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 651774.0
Subtracting 484 from 524 leaves us with 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 9:
If we divide 400 by 121, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 651774.3
Subtract 363 from 400 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
When dividing 370 by 121, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 651774.33
The remainder is 7 after subtracting 363 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 651774.33 and a remainder of 0.007.
