80701973 ÷ 124 
Our goal is to divide 80701973 by 124.

Moving on to step 1:
If we divide 8 by 124, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 124

On to step 2:
80 divided by 124 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 124

On to step 3:
124 can be fit into 807 6 times, resulting in a remainder of 63.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 744 from 807 leaves us with 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 124

Going ahead to step 4:
If we divide 630 by 124, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 620 from 630 and we're left with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 124

On to step 5:
If we divide 101 by 124, we get 0 and a remainder of 101.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
The remainder is 101 after subtracting 0 from 101.
Bring next digit (9) of the dividend behind the 101 and repeat the process: 1019 / 124

Advancing to step 6:
The number 124 fits into 1019 8 times, leaving a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 6508.0
Subtracting 992 from 1019 leaves us with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 124

On to step 7:
The number 124 fits into 277 2 times, leaving a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 65082.0
Subtract 248 from 277 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 124

Moving on to step 8:
When dividing 293 by 124, we get 2 with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 650822.0
Subtract 248 from 293 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
124 goes into 450 3 times with a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 650822.3
If we take 372 away from 450, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
If we divide 780 by 124, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 650822.36
Subtract 744 from 780 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
360 divided by 124 is 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 650822.362
Deduct 248 from 360 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
124 can be fit into 1120 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 650822.3629
If we take 1116 away from 1120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 124, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 650822.3629
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
The number 124 fits into 400 3 times, leaving a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 650822.362903
Deduct 372 from 400 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 15:
The number 124 fits into 280 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 650822.3629032
The remainder is 32 after subtracting 248 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
The number 124 fits into 320 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 650822.36290322
Subtract 248 from 320 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 650822.36290322, with a leftover of 7.2e-08.
