70389845 divided by 979 
We want to figure out the number of times 70389845 can be divided by 979.

Advancing to step 1:
979 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 979

On to step 2:
The number 979 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 979

On to step 3:
703 divided by 979 is 0 with a remainder of 703.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 703, we get 703.
Take the next digit (8) from the dividend and append it to 703, then repeat: 7038 / 979

Step 4:
When dividing 7038 by 979, we get 7 with a remainder of 185.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 6853 from 7038 and we're left with 185.
Grab the next digit (9) from the dividend, add it to 185, then carry on: 1859 / 979

Going ahead to step 5:
1859 divided by 979 is 1 with a remainder of 880.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 979 from 1859 leaves us with 880.
Grab the next digit (8) from the dividend, add it to 880, then carry on: 8808 / 979

Let's proceed to step 6:
979 goes into 8808 8 times with a remainder of 976.
The next digit of our result is 8. 
Result so far: 718.0
The remainder is 976 after subtracting 7832 from 8808.
Grab the next digit (4) from the dividend, add it to 976, then carry on: 9764 / 979

Going ahead to step 7:
979 can be fit into 9764 9 times, resulting in a remainder of 953.
The next digit of our result is 9. 
Result so far: 7189.0
Deduct 8811 from 9764 and we're left with 953.
Append the next digit (5) from the dividend to 953 and continue with: 9535 / 979

Moving on to step 8:
If we divide 9535 by 979, we get 9 and a remainder of 724.
The number 9 becomes the next digit in our result. 
Result so far: 71899.0
Deduct 8811 from 9535 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 9:
When dividing 7240 by 979, we get 7 with a remainder of 387.
Write down 7 as next digit of the result. 
Result so far: 71899.7
Subtract 6853 from 7240 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 10:
979 can be fit into 3870 3 times, resulting in a remainder of 933.
The number 3 becomes the next digit in our result. 
Result so far: 71899.73
If we subtract 2937 from 3870, we get 933.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9330, and continue the process.

Let's proceed to step 11:
The number 979 fits into 9330 9 times, leaving a remainder of 519.
The next digit of our result is 9. 
Result so far: 71899.739
If we take 8811 away from 9330, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 12:
979 can be fit into 5190 5 times, resulting in a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 71899.7395
The remainder is 295 after subtracting 4895 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 13:
When dividing 2950 by 979, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 71899.73953
If we subtract 2937 from 2950, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
If we divide 130 by 979, we get 0 and a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 71899.73953
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 15:
1300 divided by 979 is 1 with a remainder of 321.
Use 1 as the next digit of our solution. 
Result so far: 71899.7395301
If we subtract 979 from 1300, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 16:
3210 divided by 979 is 3 with a remainder of 273.
Record the quotient 3 as the next digit in the result. 
Result so far: 71899.73953013
If we subtract 2937 from 3210, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The final result is 71899.73953013 with a remainder of 2.73e-07.
