We look at the division of 70086664 by 121 
Our goal is to divide 70086664 by 121.

Going ahead to step 1:
121 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 121

Advancing to step 2:
If we divide 70 by 121, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 121

Step 3:
700 divided by 121 is 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 95 after subtracting 605 from 700.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 121

Moving on to step 4:
The number 121 fits into 958 7 times, leaving a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Deduct 847 from 958 and we're left with 111.
Fetch the next digit (6) from the dividend, attach it to 111 and continue: 1116 / 121

Step 5:
When dividing 1116 by 121, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 579.0
If we take 1089 away from 1116, we end up with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 121

Advancing to step 6:
The number 121 fits into 276 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 5792.0
Deduct 242 from 276 and we're left with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 121

Going ahead to step 7:
The number 121 fits into 346 2 times, leaving a remainder of 104.
The next digit of our result is 2. 
Result so far: 57922.0
Deduct 242 from 346 and we're left with 104.
Grab the next digit (4) from the dividend, add it to 104, then carry on: 1044 / 121

Moving on to step 8:
The number 121 fits into 1044 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 579228.0
Subtracting 968 from 1044 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
121 goes into 760 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 579228.6
Subtracting 726 from 760 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
When dividing 340 by 121, we get 2 with a remainder of 98.
The next digit of our result is 2. 
Result so far: 579228.62
Subtracting 242 from 340 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 11:
121 can be fit into 980 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 579228.628
If we take 968 away from 980, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
121 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 579228.628
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
1200 divided by 121 is 9 with a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 579228.62809
Deduct 1089 from 1200 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 14:
1110 divided by 121 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 579228.628099
The remainder is 21 after subtracting 1089 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 579228.628099 with a balance of 2.1e-06.
