We're dividing 74678561 by 620 
Our goal is to divide 74678561 by 620.

Advancing to step 1:
620 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 620

On to step 2:
620 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Grab the next digit (6) from the dividend, add it to 74, then carry on: 746 / 620

On to step 3:
746 divided by 620 is 1 with a remainder of 126.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 620 from 746, we get 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 620

Going ahead to step 4:
620 goes into 1267 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 27 after subtracting 1240 from 1267.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 620

On to step 5:
620 can be fit into 278 0 times, resulting in a remainder of 278.
Use 0 as the next digit of our solution. 
Result so far: 120.0
The remainder is 278 after subtracting 0 from 278.
Grab the next digit (5) from the dividend, add it to 278, then carry on: 2785 / 620

Step 6:
2785 divided by 620 is 4 with a remainder of 305.
Record the quotient 4 as the next digit in the result. 
Result so far: 1204.0
Deduct 2480 from 2785 and we're left with 305.
Grab the next digit (6) from the dividend, add it to 305, then carry on: 3056 / 620

Going ahead to step 7:
The number 620 fits into 3056 4 times, leaving a remainder of 576.
Put 4 as the next digit of the answer. 
Result so far: 12044.0
If we subtract 2480 from 3056, we get 576.
Include the next digit (1) from the dividend after 576, then repeat: 5761 / 620

Let's proceed to step 8:
620 can be fit into 5761 9 times, resulting in a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 120449.0
Subtract 5580 from 5761 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
620 goes into 1810 2 times with a remainder of 570.
Put 2 as the next digit of the answer. 
Result so far: 120449.2
Deduct 1240 from 1810 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 10:
620 can be fit into 5700 9 times, resulting in a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 120449.29
Subtract 5580 from 5700 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
620 goes into 1200 1 times with a remainder of 580.
The next digit of our result is 1. 
Result so far: 120449.291
Subtract 620 from 1200 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 12:
620 can be fit into 5800 9 times, resulting in a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 120449.2919
If we take 5580 away from 5800, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
620 can be fit into 2200 3 times, resulting in a remainder of 340.
Put 3 as the next digit of the answer. 
Result so far: 120449.29193
If we take 1860 away from 2200, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
620 goes into 3400 5 times with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 120449.291935
If we subtract 3100 from 3400, 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.

Let's proceed to step 15:
620 goes into 3000 4 times with a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 120449.2919354
Subtract 2480 from 3000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
The number 620 fits into 5200 8 times, leaving a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 120449.29193548
Deduct 4960 from 5200 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 120449.29193548 and a remainder of 2.4e-07.
