86941121 ÷ 124 
We want to divide 86941121 by 124.

Advancing to step 1:
8 divided by 124 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 124

Step 2:
124 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 124

Step 3:
The number 124 fits into 869 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 868 away from 869, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 124

Going ahead to step 4:
124 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 124

Advancing to step 5:
124 goes into 141 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 701.0
Subtract 124 from 141 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 124

Advancing to step 6:
124 goes into 171 1 times with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 7011.0
The remainder is 47 after subtracting 124 from 171.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 124

On to step 7:
472 divided by 124 is 3 with a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 70113.0
Deduct 372 from 472 and we're left with 100.
Fetch the next digit (1) from the dividend, attach it to 100 and continue: 1001 / 124

Going ahead to step 8:
124 goes into 1001 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 701138.0
If we subtract 992 from 1001, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 124, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 701138.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
When dividing 900 by 124, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 701138.07
If we take 868 away from 900, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
The number 124 fits into 320 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 701138.072
If we take 248 away from 320, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
124 goes into 720 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 701138.0725
The remainder is 100 after subtracting 620 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
1000 divided by 124 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 701138.07258
Subtract 992 from 1000 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
The number 124 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 701138.07258
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
The number 124 fits into 800 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 701138.0725806
The remainder is 56 after subtracting 744 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
The number 124 fits into 560 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 701138.07258064
Deduct 496 from 560 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 701138.07258064 with a remaining 6.4e-08.
