83970072 ÷ 975 
We want to divide 83970072 by 975.

On to step 1:
When dividing 8 by 975, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 975

On to step 2:
975 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 975

Moving on to step 3:
If we divide 839 by 975, we get 0 and a remainder of 839.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 839, we end up with 839.
Include the next digit (7) from the dividend after 839, then repeat: 8397 / 975

Going ahead to step 4:
If we divide 8397 by 975, we get 8 and a remainder of 597.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7800 from 8397 leaves us with 597.
Fetch the next digit (0) from the dividend, attach it to 597 and continue: 5970 / 975

Advancing to step 5:
5970 divided by 975 is 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 5850 away from 5970, we end up with 120.
Fetch the next digit (0) from the dividend, attach it to 120 and continue: 1200 / 975

Let's proceed to step 6:
When dividing 1200 by 975, we get 1 with a remainder of 225.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
The remainder is 225 after subtracting 975 from 1200.
Grab the next digit (7) from the dividend, add it to 225, then carry on: 2257 / 975

Moving on to step 7:
When dividing 2257 by 975, we get 2 with a remainder of 307.
Use 2 as the next digit of our solution. 
Result so far: 8612.0
Subtracting 1950 from 2257 leaves us with 307.
Grab the next digit (2) from the dividend, add it to 307, then carry on: 3072 / 975

Going ahead to step 8:
975 can be fit into 3072 3 times, resulting in a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 86123.0
If we subtract 2925 from 3072, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
975 goes into 1470 1 times with a remainder of 495.
The next digit of our result is 1. 
Result so far: 86123.1
If we subtract 975 from 1470, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 10:
The number 975 fits into 4950 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 86123.15
If we take 4875 away from 4950, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
975 can be fit into 750 0 times, resulting in a remainder of 750.
Write down 0 as next digit of the result. 
Result so far: 86123.15
Subtracting 0 from 750 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 12:
If we divide 7500 by 975, we get 7 and a remainder of 675.
Record the quotient 7 as the next digit in the result. 
Result so far: 86123.1507
The remainder is 675 after subtracting 6825 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 13:
The number 975 fits into 6750 6 times, leaving a remainder of 900.
Record the quotient 6 as the next digit in the result. 
Result so far: 86123.15076
Subtracting 5850 from 6750 leaves us with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Moving on to step 14:
9000 divided by 975 is 9 with a remainder of 225.
The number 9 becomes the next digit in our result. 
Result so far: 86123.150769
If we subtract 8775 from 9000, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 15:
If we divide 2250 by 975, we get 2 and a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 86123.1507692
If we subtract 1950 from 2250, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 16:
If we divide 3000 by 975, we get 3 and a remainder of 75.
The next digit of our result is 3. 
Result so far: 86123.15076923
The remainder is 75 after subtracting 2925 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

In conclusion, the division gives 86123.15076923 with a balance of 7.5e-08.
