76189661 ÷ 123 
Let's see how many times 123 fits into 76189661.

Let's proceed to step 1:
When dividing 7 by 123, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 123

On to step 2:
The number 123 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 123

Advancing to step 3:
If we divide 761 by 123, we get 6 and a remainder of 23.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 738 from 761 and we're left with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 123

On to step 4:
When dividing 238 by 123, we get 1 with a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we take 123 away from 238, we end up with 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 123

Going ahead to step 5:
1159 divided by 123 is 9 with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 619.0
If we take 1107 away from 1159, we end up with 52.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 123

Moving on to step 6:
The number 123 fits into 526 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 6194.0
If we subtract 492 from 526, we get 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 123

On to step 7:
When dividing 346 by 123, we get 2 with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 61942.0
Subtracting 246 from 346 leaves us with 100.
Take the next digit (1) from the dividend and append it to 100, then repeat: 1001 / 123

Moving on to step 8:
123 can be fit into 1001 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 619428.0
Subtracting 984 from 1001 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
If we divide 170 by 123, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 619428.1
The remainder is 47 after subtracting 123 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
When dividing 470 by 123, we get 3 with a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 619428.13
If we take 369 away from 470, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 11:
If we divide 1010 by 123, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 619428.138
The remainder is 26 after subtracting 984 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
When dividing 260 by 123, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 619428.1382
If we subtract 246 from 260, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
When dividing 140 by 123, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 619428.13821
The remainder is 17 after subtracting 123 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
170 divided by 123 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 619428.138211
The remainder is 47 after subtracting 123 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 619428.138211 and a remainder of 4.7e-06.
