80222121 ÷ 942 
Our goal is to divide 80222121 by 942.

Let's proceed to step 1:
The number 942 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 942

Step 2:
942 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 942

Advancing to step 3:
802 divided by 942 is 0 with a remainder of 802.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 802, we end up with 802.
Include the next digit (2) from the dividend after 802, then repeat: 8022 / 942

On to step 4:
8022 divided by 942 is 8 with a remainder of 486.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7536 from 8022 and we're left with 486.
Include the next digit (2) from the dividend after 486, then repeat: 4862 / 942

On to step 5:
4862 divided by 942 is 5 with a remainder of 152.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 4710 from 4862 to get 152.
Bring next digit (1) of the dividend behind the 152 and repeat the process: 1521 / 942

Moving on to step 6:
1521 divided by 942 is 1 with a remainder of 579.
Use 1 as the next digit of our solution. 
Result so far: 851.0
If we take 942 away from 1521, we end up with 579.
Bring next digit (2) of the dividend behind the 579 and repeat the process: 5792 / 942

Step 7:
5792 divided by 942 is 6 with a remainder of 140.
The next digit of our result is 6. 
Result so far: 8516.0
If we take 5652 away from 5792, we end up with 140.
Grab the next digit (1) from the dividend, add it to 140, then carry on: 1401 / 942

Going ahead to step 8:
The number 942 fits into 1401 1 times, leaving a remainder of 459.
Use 1 as the next digit of our solution. 
Result so far: 85161.0
Subtracting 942 from 1401 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

On to step 9:
942 can be fit into 4590 4 times, resulting in a remainder of 822.
The next digit of our result is 4. 
Result so far: 85161.4
Deduct 3768 from 4590 and we're left with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 10:
8220 divided by 942 is 8 with a remainder of 684.
The next digit of our result is 8. 
Result so far: 85161.48
The remainder is 684 after subtracting 7536 from 8220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 11:
The number 942 fits into 6840 7 times, leaving a remainder of 246.
Record the quotient 7 as the next digit in the result. 
Result so far: 85161.487
If we take 6594 away from 6840, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 12:
942 can be fit into 2460 2 times, resulting in a remainder of 576.
Use 2 as the next digit of our solution. 
Result so far: 85161.4872
Deduct 1884 from 2460 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 13:
When dividing 5760 by 942, we get 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 85161.48726
Deduct 5652 from 5760 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 14:
When dividing 1080 by 942, we get 1 with a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 85161.487261
If we take 942 away from 1080, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 15:
The number 942 fits into 1380 1 times, leaving a remainder of 438.
Write down 1 as next digit of the result. 
Result so far: 85161.4872611
Subtracting 942 from 1380 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final outcome is 85161.4872611, with a leftover of 4.38e-06.
